Application Functions
 Related Parameters
You set the speed at which to apply zero clamping as the zero clamping level (Pn501 or
Pn580). If you set a value that exceeds the maximum speed of the Servomotor, the actual
speed will be limited to the maximum speed of the Servomotor.
• Rotary Servomotors
• Linear Servomotors
6.5.5 /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.
Note: You can use Pn50E = n.X (/V-CMP (Speed Coincidence Detection Output) Signal Allocation) to allocate
the /V-CMP signal to different output connector pins.
Refer to the following section for details on allocations.
6.1.2
Output Signal Allocations on page 6-6
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.
