3. SIGNALS AND WIRING

		Connec-					I/O	Control
Signal	Symbol	tor pin			Functions/Applications				mode
							division
		No.						P		S	T
Proportion	PC	CN1B	Connect PC-SG to switch the speed amplifier from the				DI-1
control		8	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 signal (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 signal and torque control signal (TL) at the
			same time to make the torque less than the rated by the analog
			torque limit.
Emergency stop	EMG	CN1B	Disconnect EMG-SG to bring the servo motor to emergency stop				DI-1
		15	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.
Clear	CR	CN1A	Connect CR-SG to clear the position control counter droop pulses				DI-1
		8	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.
Electronic gear	CM1		When using CM1 and CM2, make them usable by the setting of				DI-1
selection 1			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.
Electronic gear	CM2			(Note) Input signals		Electronic gear denominator	DI-1
selection 2				CM2	CM1
				0	0	Parameter No. 3 (CMX)
				0	1	Parameter No. 69 (CM2)
				1	0	Parameter No. 70 (CM3)
				1	1	Parameter No. 71 (CM4)
			Note. 0: CM1/CM2-SG off (open)
				1: CM1/CM2-SG on (short)
Gain changing	CDP		When using this signal, make it usable by the setting of				DI-1
			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.
