11-2
11.2.1 Input contact signal function and use table
Name Pin No. Function and Use
SVONEN 18
ON: Servo start command
OFF: Servo start command reset
DIR 16
Selects servo rotation direction[Valid only in speed control mode]
(Off: Command direction rotation, ON: Counter-command direction
rotation)
STOP/
START
13
Forcibly zeros (stops) the speed command value, or starts
operation. (Can be selected from parameter P2-29)
CCWLIM 15
OFF: Motor CW running limited
ON: Motor CW running allowed
CWLIM 40
OFF: Motor CCW running limited
ON: Motor CCW running allowed
ESTOP 39
Forcibly ignores all input status of the servo drivers in case of
external emergency, and shuts off (free-run) motor operation after
rapidly decelerating the motor.
(Contact type can be selected from parameter P2-30)
ALMRST 38 Resets alarm status if turned ON
PI/P 41
Selects speed control mode (Turned OFF during normal operation)
ON: Proportional control, OFF: Proportional integration control
Valid only in speed control mode.
TLIM 14
ON: Analog torque limit; Off: Digital torque limit.
Valid only in speed control mode.
Selects rotation speed command by combination of the two signals
(In speed control mode).
SPD1
SPD2
43
17
Slects electronic gear by conbination of the two signals(In position
control mode).
TYPE 42
ON: Operates as speed servo.
OFF: Operates as position servo.
Where ON: Applicable contact is connected to "GND24".
OFF: Applicable contact is connected to "+24V", or applicable contact not connected.

RDY 21
ON: Main power and auxiliary power are connected to servo
without any alarm.
ON: Motor speed reached designated level.
Valid only in speed control mode
INSPD 22
Reached designated pulse position (Position control)
ZSPD 47 ON: Motor speed is zero.
BRAKE 48
Output signal for external machine brake drive

A_CODE2
45
19
44
Displays alarm type.
See the table below [Alarm Code output status].
TRQOUT 46 ON: Servo is under torque limit.
Where ON: Applicable contact is connected to "GND24".
OFF: Applicable contact is connected to "+24V", or applicable contact not connected.
