5. PARAMETERS
5.3.3 Analog monitor
The servo status can be output to two channels in terms of voltage. The servo status can be monitored using
an ammeter.
(1) Setting
Change the following digits of parameter No.PC09, PC10.
Analog monitor (MO1) output selection
(Signal output to across MO1-LG)
Analog monitor (MO2) output selection
(Signal output to across MO2-LG)

Parameter No.PC09
Parameter No.PC10
Parameters No.PC11 and PC12 can be used to set the offset voltages to the analog output voltages. The
setting range is between
999 and 999mV.
Parameter No. Description Setting range [mV]
PC11 Used to set the offset voltage for the analog monitor 1 (MO1).
999 to 999
PC12 Used to set the offset voltage for the analog monitor 2 (MO2).
(2) Set content
The servo amplifier is factory-set to output the servo motor speed to analog monitor 1 (MO1) and the torque
to analog monitor (MO2). The setting can be changed as listed below by changing the parameter No.PC14
and PC12 value.
Refer to (3) for the measurement point.

Note. The feedback position is output based on the position data passed between servo system controller and servo amplifier. The
parameter number No.PC13/PC14 can set up the standard position of feedback position that is output to analog monitor in order
to adjust the output range of feedback position. The setting range is between
99999999 and 99999999 pulses.

5.3.4 Alarm history clear
The servo amplifier stores one current alarm and five past alarms from when its power is switched on first. To
control alarms which will occur during operation, clear the alarm history using parameter No.PC21 before
starting operation.
Clearing the alarm history automatically returns to "
0 ".
After setting, this parameter is made valid by switch power from OFF to ON.
