Here is an example.
It assumes that the motor speed is 0 rpm, then the analog monitor voltage output should be 0 V.
This difference above is 0.5 V, which could be compensated by setting PC28 or PC29 as -500mV so the MOD analog
voltage would be corrected.
Output proportion of analog monitor
The output proportion of analog monitor enables users to set the ratio of the analog voltage output to be viewed. Relevant
parameters are presented in the table below.

If the current rotation speed is ±3000 rpm and monitor scale is ±10V/ (double rated speed), the analog output should be
+5V if MOG1 or MOG2 is set as initial value(100%). So, the analog monitor output voltage by MON should be +10V in
case of 50% setting value applied.
The equation is:

6.6.3 Operation of electromagnetic brake interlock
The electromagnetic brake interlock signal is described: (1)As MBR is OFF , the electromagnetic brake is disabled
and motor shaft is locked. (2)As MBR is ON
,
the electromagnetic brake is enabled and motor shaft is rotatable. The PC16
could be used to decide the delay time of SON signal off to MBR signal activated. The electromagnetic brake is usually
applied on the Z axis (vertical axis) prevent from load falling.
Electromagnetic brakes normally used on the z axis (vertical axis) direction to lower servo motor ‘s resistance that
produces overheat which would result in the decreasing of motor cycle life. Electromagnetic brake must be operated in
the servo OFF situation. Brake signal can control brake to be magnetic; provide electromagnetic brake power, and make
electromagnetic brake open.
• MBR enables/disables magnetic contactor to release/lock the motor shaft.
• The coil of electromagnetic brake is without polarity.
• Do not use 24Vdd) to drive the electromagnetic brake.
• If users control the electromagnetic brake without MBR DO, refer to the operation sequence.
• If want to turn on the function of DO MBR, please set the PA01 to X1XX.
