Power of the external load torque( PL)=TL × ω
Where:
TL
：
is the external load torque. (Unit: Nt-m)
ω
：
is the motor rotation speed. (Unit: rad/s)
Please calculate this value at safe condition as possible as you can.
If an external load torque of +50% rated torque is applied and the servo motor speed is 3000r/min, the servo drive
is 400W capacity(rated torque: 1.27Nt-m), then the users need to connect a external brake resistor which power is 2 x (0.5
x 1.27) x (3000 x 2 x π/ 60) = 399W, 100Ω.
Note : 1rpm = 2π

6.6.2 Analog monitor output
There are 2 analog monitor channels(MON1
、
MON2) whose address is in CN1-30(MON1) and CN1-32(MON2) provided
for users to check the required signals. The contents and settings of monitor output are described in the table below.

There are 2 monitor outputs, ch1 and ch2.
0 ch2 0 ch1
The setting values and their corresponding output are
listed below.
0:Motor speed (scale: ±10V/(double rated speed))
1:Generated torque (scale: ±10V/max.torque)
2:Speed command (scale: ±10V/(double rated speed))
3:Effective load ratio (scale: ±10V/±300%)
4:Pulse command frequency (scale: ±10V/500kpps)
5:Current command (scale: ±10V/max.current command)
6:DC Bus voltage (scale: ±10V/400V)
7:Pulse command error (scale:±10V/1048576 pulse)

Example:
If the PC14 is set as 0000 and the current speed of motor is forward rotation ±3000 rpm(± means forward/reserve
rotation), a +5V signal would be measured on CN1-30. The mentioned example above is without any adjustment of PC28
to PC31.
Voltage offset of analog monitor
The parameter PC28 and PC29 are used to set the compensation to eliminate the bias voltages of analog monitor output
MON1 and MON2. Description as followings.
