Power of the external load torque:
L
L
P
T
Where:
L
P
is the power of external load torque
L
T
is the external load torque. (Unit: Nt-m)
ω
is the motor rotation speed. (Unit: rad/s)
For example:
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/60 (rad/s)

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/4194304 pulse)
8
:
Pulse command error(scale: ±10V/10000pulse)
9
:
Pulse command error(scale: ±10V/100pulse)
Example
:
If the PC14 is set as 0000h and the current speed of motor is forward rotation 3000 rpm, a +5V signal
would be measured on CN1-30 and LG. On the other hand, a
-5V signal would be detected if the speed
