5 DATA USED FOR POSITIONING CONTROL
Pr.123 Option function 1
Set the option function 1 (carrier frequency selection, serial encoder cable
selection).
•
Carrier frequency selection (low acoustic noise mode selection)
Select the carrier frequency of "1: 9.0KHz" to reduce the electromagnetic sound
generated by the servomotor by about 20dB.
At this time, the continuous output of the servomotor reduces.
•
Serial encoder cable selection
Select the serial encoder cable to be used.

0:2.5KHz (Standard)
3:9.0KHz (Low noise)
0:2-wire
1:4-wire (Supports long distance cables)
Pr.124 Option function 2
Set the option function 2 (motor-less operation selection, solenoid brake interlock
output selection).
•
Motor-less operation selection
When motor-less operation is valid, signals can be output or the status displayed
without connection of the servomotor.
•
Solenoid brake interlock output selection
Selection of "0: Independent of motor speed (Output under specific condition)"
provides output in any of the following statuses regardless of the servomotor
speed.
1) Servo OFF
2) During alarm occurrence
3) Emergency stop input is OFF (valid)
Selection of "1: Output under specific condition at motor speed of zero speed or
less" provides output in any of the above statuses 1) to 3) and under the
condition that the servomotor speed is equal to or less than "
Pr.130
Zero
speed". Use " Pr.121
Solenoid brake output" to set the time from when the
solenoid brake interlock signal is output until the servo amplifier shuts OFF the
base circuit.
