PC22 *COP1 Function selection C-1
Select the execution of automatic restart after instantaneous
power failure selection, and encoder cable communication system
selection.
00
Restart after instantaneous power failure selection
If the power supply voltage has returned to normal
after an undervoltage status caused by the reduction
of the input power supply voltage in the speed control
mode, the servo motor can be restarted by merely
turning on the start signal without resetting the alarm.
0: Invalid (Undervoltage alarm (AL.10) occurs.)
1: Valid
Encoder cable communication system selection
0: Two-wire type
1: Four-wire type
The following encoder cables are of 4-wire type.
MR-EKCBL30M-L
MR-EKCBL30M-H
MR-EKCBL40M-H
MR-EKCBL50M-H
The other encoder cables are all of 2-wire type.
Incorrect setting will result in an encoder alarm 1 (AL.
16) or encoder alarm 2 (AL. 20).

PC23 *COP2 Function selection C-2
Select the servo lock at speed control mode stop, the VC-VLA
voltage averaging, and the speed limit in torque control mode.
Selection of servo lock at speed control mode stop
0: Valid
1: Invalid
Selection of speed limit for torque control
0: Valid
1: Invalid
Do not use this function except when configuring
a speed loop externally.
If the speed limit is invalid, the following
parameters can be used.
Parameter No. PB01 (filter tuning mode)
Parameter No. PB13 (machine resonance
suppression filter 1)
Parameter No. PB14 (notch shape selection 1)
Parameter No. PB15 (machine resonance

VC/VLA voltage averaging
Used to set the filtering time when the analog
speed command (VC) voltage or analog speed limit
(VLA) is imported.
Set 0 to vary the speed to voltage fluctuation in real
time. Increase the set value to vary the speed
slower to voltage fluctuation.
