		Switch					Setting details
	CNT1		SER_A		Connects the Servo #1 phase A to the Motion Control
	SER_A				Module's CNT1 phase A.
			TER_A		Connects the external encoder phase A to the Motion
					Control Module's CNT1 phase A. (See note a.)
	CNT1		SER_B		Connects the Servo #1 phase B to the Motion Control
	SER_B				Module's CNT1 phase B.
			TER_B		Connects the external encoder phase B to the Motion
					Control Module's CNT1 phase B. (See note a.)
	CNT1		SER_Z		Connects the Servo #1 phase Z to the Motion Control
	SER_Z				Module's CNT1 phase Z.
			TER_Z		Outputs the Servo #1 phase Z output from the terminal.
	DA2		Y axis		Connects FQM1-MMA21 analog output 2 to Servo #2
					REF.
			X axis		Connects FQM1-MMA21 analog output 2 to Servo #1
					TREF.
	AD		VOL		Sets analog inputs as voltage inputs.
			CUR		Sets analog inputs as current inputs. (See note b.)

Note (a) An external encoder with a line-driver output can be connected.

(b)For 4 to 20 mA current inputs, voltage input (+) and current input do not need to be connected.

7.Terminating Resistance Switch

Set this terminating resistance switch to ON when the Servo Relay Unit is at the end of the RS-422A line and the PORT2 terminal is not connected to PORT1 on another Servo Relay Unit.

TERM

ON

SW6

OFF

8.Servo Driver Phase B Switches

When the high-speed counter is set to absolute mode CW in the System Setup, inputs are the inverse of the phase from the encoder output phase B from the Servo Driver. The high-speed counter is used in incremental mode for all other System Setup settings.
