Function
Encoder phase A+ Encoder signals (or external scale signals during full closing control) are output according En-
coder Dividing Numerator parameter.
Encoder phase A-
This is the line-driver output (equivalent to R422). The maximum output frequency is 4 Mbps.
Encoder phase B+
Phase Z is output for encoder signals (or external scale signals during full closing control). This
Encoder phase B-
is the line-driver output (equivalent to R422).
Encoder phase Z+
Encoder phase Z-
Encoder phase-Z output Phase Z is output for encoder signals (or external scale signals during full closing control).
Encoder phase-Z common
Open-collector output.
Brake release signal output Timing signal for operating the electromagnetic brake on a motor.
Servo ready: ON if there is not servo alarm when the control/main circuit power supply is turned ON.
Servo alarm: turns OFF when an error is detected.
Motor rotation speed detection. This output turns ON when the motor rotation speed reaches the speed set in a parameter.
Positioning complete output 1: turns ON when position error is equal to setting parameter.
Position complete output 2 The function of output signals allocated to pins 11,10, 34 to 39 can be changed with these op-
tions by parameters settings.

Function
External scale power supply output. Use at 5.2V +/-5% and at or below 250 mA.
This is connected to the control circuit ground connected to connector CN1.
External scale signal I/O (serial signal).
External scale signal input (Phase A, B, and Z signals). Perfoms the input and output of phase A, B and Z signals.
Shield ground
Function
Analog monitor output 1. Outputs the analog signal for the monitor. Use the parameters setting to select the output
to monitor.
Default setting: Motor rotation speed 1 V/(1000 r/min).
Analog monitor output 2. Outputs the analog signal for the monitor. Use the parameters setting to select the output
to monitor.
Default setting: Motor rotation speed 1 V/(1000 r/min).
Ground for analog monitors 1,2.
