Proportion

control

PC CN1B

Connect PC-SG to switch the speed amplifier from the

proportional integral type to the proportional type.

If the servo motor at a stop is rotated even one pulse due to any

external factor, it generates torque to compensate for a position

shift. When the servo motor shaft is to be locked mechanically

after positioning completion (stop), switching on the proportion

control (PC) upon positioning completion will suppress the

unnecessary torque generated to compensate for a position shift.

When the shaft is to be locked for a long time, switch on the

proportion control (PC) and torque control (TL) at the same time

to make the torque less than the rated by the analog torque limit.

DI-1

Emergency stop EMG CN1B

Turn EMG off (open EMG-common) to bring the motor to an

emergency stop state, in which the base circuit is shut off and the

dynamic brake is operated.

Turn EMG on (short EMG-common) in the emergency stop state

to reset that state.

DI-1

Clear CR CN1A

Turn CR on 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 is on.

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 and CM2 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.

Gain changing CDP When using this signal, make it usable by the setting of

parameter No. 43 to 48.

Turn CDP on 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.
