PosmoA Commissioning

SIMODRIVE POSMO A is an intelligent distributed positioning motor connected as node to the PROFIBUS DP field bus. SIMODRIVE POSMO A can be operated via PROFIBUS DP. This means that all of the signals and data required to commission (start–up) and operate the drive and also to evaluate faults are transferred via PROFIBUS.

1 Hardware connection

• Check the PROFIBUS shielding

• Check that the Grounding cables are installed and the screws are tight

2 Adjust PROFIBUS Address

Adjust the same Address indicated in the drawings. If the Drive is the last PROFIBUS member at this loop, switch on the Bus termination resistors (Dip 9 and 10)

Template:Image Switch on supply If the LED on the unit is permanently green, the PROFIBUS is Okay and the Drive is ready

3 Download the Configuration From Simatic Manager

• Check your Interface-Settings in the Simatic Manager (Interface must be assigned)
• Close the Siemens Starter Software also, otherwise you can't go online later
• Open the Offline-Configuration from the SIMATIC-Manager by double click on the Parameter Set

• SimocomA Software will start
• After the Software detected the drive online, press download Template:Image
• Copy Ram to Rom to store the settings permanently Template:Image

4 Default Parameters

In case you have no default Parameter file, there are not so many settings to take care of

• Traversing Blocks: No 3 and 4 are used for traversing. Important is to set Traversing Type to Absolute and Acceleration to 20%

• Mechanics: Adjust the pitch and positive direction according to your mechanical system

• Limitations: Max. Velocity needs to be adjusted that the Motor speed doesn't exceed the max Motor speed. This Velocity needs to be same like in the PVSS

6 Calibration

Calibration is only done from the PVSS Parameter Panel. Make sure that both Power Supplies (3L+/3M and 5L+/5M) are okay at the drive. Without them the calibration will fail.
Also the Safety Software can switch of this power supply!

7 Troubleshooting

The Alarm Value in PVSS is Bit Coded. E.g. a value of 256 results in the P947.8 Alarm

PVSS Fault Value	Error Bit	Error Number Posmo	Description	Cause	Remedy
1	P947.0	700	Overvoltage	The load voltage has exceeded 35 V (75 W motor) or 60 V (300 W motor). When braking, the braking energy is excessive which causes an inadmissible increase in the load voltage.	Provide regenerative feedback protection.
2	P947.1	701	Undervoltage of the load current supply	The load voltage has fallen below 17 V. The load power supply is overloaded. SITOP: The load voltage was powered-down when braking due to overvoltage. The following applies as of SW 3.0: this fault only occurs if the drive is to be switched from follow-up mode to control mode. If no enable signals are set in the control word and only the power supply to the electronics is switched on, the alarm ”Undervoltage load power supply” is signalled. This alarm automatically disappears when the load power supply is switched in.	Increase load power supply rating. SITOP: Provide regenerative feedback protection.
4	P947.2	702	Electronics temperature	The electronics temperature is > 90 degrees Celsius and has been present for longer than specified in P29 (electronics temperature tolerance time). An excessive electronics temperature is first signaled using warning 800 (warning, electronics temperature). The ambient temperature is too high.	Observe the de-rating characteristic. Reduce ambient temperature.
8	P947.3	703	Overcurrent fault	The current limit has been exceeded. The motor or the electronics is defective.	Replace the positioning motor.
16	P947.4	704	Encoder fault	The signal sequence for the rotor position identification is not permissible. The number of increments between two rotor position signals lies outside the permissible tolerance. The motor or the electronics is defective.	Replace the positioning motor.
32	Bit5	705	Standstill monitoring	The motor was moved out of the standstill area (P14) in the closed-loop controlled status. Note: The fault can be changed-over to a warning using P30 (fault suppression).	Check P14 (standstill area).
64	P947.6	706	Software limit switch, start	The actual position lies outside the range defined by the software limit switch. When traversing to a software limit switch, the motor is always stopped. SW 1.6 and higher: This fault is also signalled if the traversing range limits of the axis (+/– 200000mm or degrees or inches) are reached. In this case, the Additional information 910 (P954.10) is output. SW 2.0 and higher: This error is also output when the corresponding hardware limit switch (start) has been overrun. In this case, additional information 911 (P954.11) is output. Note: The fault can be changed-over to a warning using P30 (fault suppression).	Move away in the opposite direction. Check P6 (software limit switch, start).
128	P947.7	707	Software limit switch, end	The actual position lies outside the range defined by the software limit switch. When traversing to a software limit switch, the motor is always stopped. SW 1.6 and higher: This fault is also signalled if the traversing range limits of the axis (+/– 200000mm or degrees or inches) are reached. In this case, the Additional information 910 (P954.10) is output. SW 2.0 and higher: This error is also output when the corresponding hardware limit switch (end) has been overrun. In this case, additional information 911 (P954.11) is output. Note: The fault can be changed-over to a warning using P30 (fault suppression).	Move away in the opposite direction. Check P7 (software limit switch, end).
256	P947.8	708	Speed controller at stop	The speed controller is at its limit for more than 200 ms. The required speed is not reached. The load or friction is too high or the drive is too small. The current limit (P28, P16) is set too low. The drive is defective. Note: The fault can be changed-over to a warning using P30 (fault suppression).	Reduce load. Increase current limit. Replace the positioning motor. Check the drive parameterization.
512	P947.9	709	Bus communications	Bus communications between the master and slave has failed. The bus cable has been withdrawn or is defective The EMC faults on the bus cable are too high.	Check fieldbus.
1024	P947.10	710	Hardware watchdog reset	After a restart, after initiating the CPU monitoring, the positioning motor goes into a fault condition. Note: The following applies from SW 1.3: Afterwards the positioning motor is no longer referenced.	Posmo A 75W : Replace the positioning motor. Posmo A 300W : Replace the drive unit.
2048	P947.11	711	Flying measurement/actual value setting	Cause The ”flying measurement/actual value setting” function has not been correctly parameterized. The bit combination for the program control word (PSW) is illegal. No function is executed. When the function is running, terminal 1 was re-parameterized as output. The motion is cancelled and the axis is braked with the maximum deceleration. From SW 2.1: This fault is also signaled if a fault has occurred during the execution of the function ”Reference to occurring zero mark” (see P80, P31/32, P56). In this case, the supplementary information 912 is also signaled. The function ”Reference to occurring zero mark” cannot be used in conjunction with P80:x.9, P80:x.10 or P80:x.11.	Check program control word (PSW.9, PSW.10, PSW.11). Check terminal parameterization (P31 = 27 or other input parameterization).
4096	P947.12	712	Holding brake, undervoltage	At least the following voltage characteristics are required in order to open and hold the integrated holding brake: Open Load power supply > 24 V Stop Load power supply > 18 V The drive is stopped if the load power supply voltage is too low. Note: This fault can be disabled for a motor without holding brake (P56.5 = 0).	Check the load power supply and increase rating.
8192	P947.13	713	Reference position lost	During shutdown, the drive was in motion. Therefore, the reference positon has not been accepted. The drive is not referenced.	Reference drive.
16384	P947.14	714	Error in the FEPROM	We have detected a fault in the non-volatile memory (FEPROM).	Evaluate P954
32768	P947.15	715	System error	An internal fault was detected in the drive.	Activate/deactivate positioning motor. Check and correct the motor data. Posmo A 75W : Replace the positioning motor. Posmo A 300W : Replace the drive unit.
