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.
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 "
cleared while CR-SG are connected.
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.

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.
<Position/internal speed control change mode>
Used to select the control mode in the position/internal speed
control change mode.

CN1-23 Used to enter a command pulse train.
In the open collector system (max. input frequency 200kpps):
CN1-25 Forward rotation pulse train across PP-SG
Reverse rotation pulse train across NP-SG
CN1-22 In the differential receiver system (max. input frequency 500kpps):
Forward rotation pulse train across PG-PP
CN1-24 Reverse rotation pulse train across NG-NP
The command pulse train form can be changed using
parameter No. 21.
