Application Functions
Note: 1. You must allocate the /S-RDY signal to use it. Use Pn50E = n.X
(/S-RDY (Servo Ready) Signal Allo-
cation) to allocate the signal to a connector pin. Refer to the following section for details.
7.1.2 Output Signal Allocations
2. Refer to the following section for information on the hard wire base block and the /S-RDY signal.

/V-CMP (Speed Coincidence Detection) Signal
The /V-CMP (Speed Coincidence Detection Output) signal is output when the Servomotor
speed is the same as the reference speed. This signal is used, for example, to interlock the
SERVOPACK and the host controller. You can use this output signal only during speed control.
The /V-CMP signal is described in the following table.
Note: You must allocate the /V-CMP signal to use it. Use Pn50E = n.
X
(/V-CMP (Speed Coincidence Detec-
tion Output) Signal Allocation) to allocate the signal to connector pins.
Refer to the following section for details on allocations.
You can set the speed detection width for the /V-CMP signal in Pn503 (Speed Coincidence
Signal Detection Width) for a Rotary Servomotor or in Pn582 (Speed Coincidence Signal
Detection Width) for a Linear Servomotor.
•
Rotary Servomotors
The signal is output when the difference between the reference speed and motor speed is
equal or less than the setting.
•
Linear Servomotors
The signal is output when the difference between the reference speed and motor speed is
equal or less than the setting.
