Corrected from:
Library: L_MC1P_MotionControlBasic (FAST Motion) V03.17.00.226
(update via package manager)
Response of the new version:
The status information of the homing function will be processed correct now.
Homing is possible now, with i700, external encoder (EPM-S602) and 'PosControl PLC'.
What happens?
After completion of homing, the 'xIsHomed' status is not set and, accordingly, positioning cannot be started.
When does this behaviour occur?
i700 servo inverter in the V/f characteristic control motor control mode for asynchronous motor (ASM) operation without motor encoder and
position control via the controller ('PosControl PLC') with an external encoder connected to the controller via the backplane bus.
Which products are affected?
Library: L_MC1P_MotionControlBasic (FAST Motion)
(contained in the PLC Designer)
Short-term measures:
The 'xIsHomed' status is not set because, due to the non-existent resolver, a corresponding status information is internally sent to the control system.
This status information can be avoided by plugging a dummy plug onto the resolver input to simulate a resolver.
Dummy plug (Sub-D) with the following interconnection:
- 1kOhm between pin 1 to pin 9,
- 1kOhm between pin 4 to pin 9 and
- 1kOhm between pin 6 to pin 9.
