Sequence output signal These signals allocate the following functions according to the 
settings of Output Signal Selections 1 to 4 (Pn410 to 413).
BKIR [11] Brake interlock output Outputs the timing signal for operating 
the electromagnetic brake on a motor.
√√√√
BKIRCOM 
[10]
READY [35] Servo ready completed This output signal indicates the Drive is 
ready to be energized.
It is turned ON when the control and 
main power supply is established and 
not in alarm status.
√√√√
READYCO
M [34] 
/ALM [37] Servo alarm The output is OFF when an alarm is 
generated for the Servo Drive.

ALMCOM 
[36]
INP1 [39] Positioning completion 
output 1
If the position error is equal to 
Positioning Completion Range 1 
(Pn431) or less, this output turns ON 
according to the setting condition of 
Positioning Completion Condition 
Selection (Pn432).
√√
INP1COM 
[38]
TGON [39] Motor rotation speed 
detection output
This output turns ON when the motor 
rotation speed reaches the speed set in 
Rotation Speed for Motor Rotation 
Detection (Pn436).
√√
TGONCOM 
[38]
TLIMT Torque limit output This output turns ON while the torque is 
limited.
√√ √
TLIMTCOM
ZSP Zero speed detection 
signal
This output turns ON when the motor 
rotation speed is equal to Zero Speed 
Detection (Pn434) or less.
√√√√
ZSPCOM
VCMP Speed conformity 
output
This output turns ON when the 
command speed corresponds to the 
motor rotation speed.
This output turns ON when the 
difference between the command speed 
and motor rotation speed is inside the 
setting range of Speed Conformity 
Detection Width (Pn435).
√√
VCMPCOM
INP2 Positioning completion 
output 2
If the position error is equal to 
Positioning Completion Range 2 
(Pn442) or less, this output turns ON 
according to the setting condition of 
Positioning Completion Condition 
Selection (Pn432).
√√
INP2COM
WARN1 Warning output 1 This output turns ON according to the 
setting condition of Warning Output 
Selection 1 (Pn440).
