13.2 Analog monitor
The detected speed and detected torque can be output as voltages from pin 7 (V-MON output) and pin 9
(T-MON output) of the analog I/O connector (CN6), respectively.
Use this function if you want the output voltage to be monitored by a programmable controller, etc.
Output voltage: ±10 VDC

Analog speed monitor
Set the analog speed monitor using the following application parameters:
• Analog speed monitor maximum value [APP-2-07]
Sets the maximum value of detected speed to be monitored.
• Analog speed monitor maximum voltage [APP-2-08]
Sets the voltage at which to detect the maximum speed.
• Analog speed monitor offset voltage [APP-2-09]
This parameter is set when the home position of output voltage is to be offset.

Description
① 6000 r/min 10 V 0 V
When the detected speed is 6000 r/min,
10 V is output.
② 3000 r/min 3 V 0 V
When the detected speed is 3000 r/min,
3 V is output. The voltage does not rise
above 3 V even when the detected speed
exceeds 3000 r/min.
③ 3000 r/min 10 V 0 V
When the detected speed is 3000 r/min,
10 V is output.
④ 6000 r/min 10 V 1 V
The home position of output voltage
becomes 1 V.

Note
Even when a speed above the maximum voltage is detected, the output will not exceed
the maximum voltage.
