P S
Emergency stop EMG CN1-8 Disconnect EMG-SG to bring the servo motor to emergency stop
state, in which the servo is switched off and the dynamic brake is
operated.
Connect EMG-SG in the emergency stop state to reset that state. DI-1
Clear CR CN1-5 Connect CR-SG to clear the position control counter droop pulses on
its leading edge. The pulse width should be 10ms or more.
When the parameter No.42 setting is " 1 ", the pulses are always
cleared while CR-SG are connected. DI-1
Electronic gear
selection 1 CM1 When using CM1 and CM2, make them usable by the setting of
parameters No. 43 to 48.
The combination of CM1-SG and CM2-SG gives you a choice of four
different electronic gear numerators set in the parameters.
CM1 and CM2 cannot be used in the absolute position detection
system. DI-1

Gain changing CDP When using this signal, make it usable by the setting of parameter
No. 43 to 48.
Connect CDP-SG to change the load inertia moment ratio into the
parameter No. 61 setting and the gain values into the values
multiplied by the parameter No. 62 to 64 settings. DI-1
Control change LOP <Position/internal speed control change mode>
Used to select the control mode in the position/internal speed
control change mode. DI-1

Used to enter a command pulse train.
In the open collector system (max. input frequency 200kpps):
Forward rotation pulse train across PP-SG
Reverse rotation pulse train across NP-SG
In the differential receiver system (max. input frequency 500kpps):
Forward rotation pulse train across PG-PP
Reverse rotation pulse train across NG-NP
The command pulse train form can be changed using
parameter No. 21.
