* 1. The voltage is increased 10 times if DD motor is used.
* 2. Torque reference after gravity compensation (Pn411)
* 3. In the case of speed control, the monitor signal for position deviation is
indefinite.
* 4. Gap (0.01V/pulse) is output if Drive Clearance Control is active.
Monitor magnification can be set as follows:

Monitor magnification: 10
2 Monitor magnification: 100
3 Monitor magnification: 1/10
4 Monitor magnification: 1/100
Analog monitor output voltage is ± 10 V max. MD3003 must be set so that maximum voltage is not
exceeded.
