10-7 Duty (load factor) monitor
The SRCP30 controller has a duty (load factor) monitor to allow you to operate the robot under the
most optimal conditions. The duty monitor checks the robot's motor load factor and displays it in
percent (%) versus the motor rating.
An overload error might appear if the duty exceeds 100% during robot operation. If this happens,
either lower the robot acceleration or maximum speed, or increase the robot stop time (lower the duty
ratio). On the other hand, if you want to shorten the cycle time even further, when there is currently
no overload, you can raise the acceleration or maximum speed, or shorten the robot stop time (raise
the duty ratio).
There are the following two methods to measure the duty.
Method 1: On the TPB, select DUTY mode and measure the duty during robot movement
with a pulse train input (Pulse Train mode) or dedicated command input (Normal
mode).
Method 2: Specify an interval in a program in which you want to measure the duty and run the
program.
[Method 1]
1) Operate the robot with a pulse train input (Pulse Train mode) or dedicated command input
(Normal mode).
2) On the TPB, select DUTY mode.
3) Measure the operation duty.
4) Check the measurement result.
Refer to "10-7-1 Measuring the duty (load factor)" for procedures to start and stop duty measurement
and check the result.

NOTE
In method 1, the duty cannot be measured during robot movement by the TPB (RS-232C).
