/V-CMP (Speed Coincidence Detection) Signal

The /V-CMP (Speed Coincidence 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.
Type
Output
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
Detection Signal Output Width) for a Rotary Servomotor or in Pn582 (Speed Coincidence
Detection Signal Output Width) for a Linear Servomotor.
• Rotary Servomotors
Pn503
The signal is output when the difference between the reference speed and motor speed is
equal or less than the setting.
Example
• Linear Servomotors
Pn582
The signal is output when the difference between the reference speed and motor speed is
equal or less than the setting.

Output Signal Allocations
Speed Coincidence Detection Signal Output Width
Setting Range Setting Unit
0 to 100
If Pn503 is set to 100 and the speed reference is 2,000 min
when the motor speed is between 1,900 and 2,100 min
Motor speed
The /V-CMP signal is output when the motor speed is in
the area between the dotted lines.
Speed Coincidence Detection Signal Output Width
Setting Range Setting Unit
0 to 100
If Pn582 is set to 100 and the speed reference is 2,000 mm/s the signal would be output
when the motor speed is between 1,900 and 2,100 mm/s.
Motor speed
The /V-CMP signal is output when the motor speed is in
the area between the dotted lines.
