Commissioning steps
Input of parameter values via STARTER dialog or expert list:
● p4400 = 1 (encoder emulation by means of encoder position actual value)
● p4420 = r0479[n] (SERVO or VECTOR), n = 0 ..2
● p0010 = 4 (encoder commissioning TM41)
● p0408 = pulse number of the motor encoder from SERVO/VECTOR
● p0418 = fine resolution of the motor encoder from SERVO/VECTOR
● p0010 = 0 (comple encoder commissioning TM41)
Note
To be able to signal encoder emulation faults from the TM41 to a higher-level external
control, parameter r2139.0...8 CO/BO: status word faults/alarms 1 must be interconnected
by BICO with a digital output (TM41 or CU) which can be read by the external control
system.
Other sequences:
1. A fault message appears (F35228). This indicates that the sampling time for encoder
2. Copy from RAM to ROM.
3. POWER ON reset (also acknowledges fault message).
