Analog Override - Mitsubishi MR-JE-200A Instruction Manual

2. SIGNALS AND WIRING

2.4 Analog override

You can change the servo motor speed by using VC (Analog override). The following table shows signals
and parameters related to the analog override.
(1) VC (Analog override)
You can continuously set changed values from outside by applying voltage (-10 to +10 V) to VC (Analog
override). The following shows percentage of the actual speed to input voltage and set speed.
POINT
When using the analog override in the point table method or program method,
enable OVR (Analog override selection).
The following shows functions whether usable or not with the analog override.
(1) Analog override usable
Automatic operation mode (point table method/program method)
JOG operation in the manual operation mode
Automatic positioning to home position function in the point table method
(2) Analog override unusable
Manual pulse generator operation in the manual operation mode
Home position return mode
Test operation mode using MR Configurator2 (positioning operation/JOG
operation)
