Question:
How can I commission a synchronous motor with absolute value encoder at 9300 servo drive?
Answer:
1. Make electrical installation (mains supply, motor, feedback etc.)
2. Set controller inhibit at terminal 28 => low
3. Swich on voltage supply
4. Establish communication with controller for commissioning via PC or plug in keypad
5. C0173: Set correct mains voltage (e. g. for 400 V = 1)
6. C0086: Select motor
7. C0025: Select encoder type (309 ... 311 = SingleTurn; 409 ... 411 = MultiTurn)
8. C0421 = 8 V; Set voltage supply for absolute value encoder
9. If necessary, adjust the rotor position (see e. g.
200415295 or Manual), if
a)
no Lenze motor is used or
b) after changes of the motor feedback, e. g. a defect encoder exchange.

. SAVE parameter under C0003 = 1
11.
SWITCH OFF and ON POWER SUPPLY of controller!
12. After setting-up further application-relevant parameters, enable the controller (terminal 28 = high) and enter speed setpoint via selected setpoint channel
To ensure an error-free operation, the controller must recognise the rotor position of the motor. If an absolute value encoder is set as feedback system (C0025) and connected at X8 when the supply voltage (power or 24 V) is switched on
• the absolute position (rotor position) is read from the absolute value encoder via the serial Hiperface interface (RS485) and
• the internal pole position is calculate from this value
during initialisation.
This procedure implies that a troublefree operation is possible only after saving
and mains switching once an absolute value encoder has been selected.
