10-4 Manual Tuning
As described before, the OMNUC G5 Series have a realtime autotuning function. However,
when the gain cannot be properly adjusted due to restrictions such as load conditions even if
realtime autotuning is performed, or when the optimum responsiveness or stability is required
to match each load, readjustment maybe required.
This section describes how to perform manual tuning for each CONTROL mode and function.
Basic Settings
Before Manual Setting
More reliable adjustment can be performed quickly by using waveform monitoring with the data
tracing function of CX-Drive or by measuring the analog voltage waveform with the monitor
function.
Analog Monitor Output
The actual motor speed, command speed, torque, and number of accumulated pulses can be
measured in the analog voltage level using an oscilloscope or other device. The type of signal
to output and the output voltage level are set with Analog Monitor 1 Selection (Pn416) and
Analog Monitor 2 Selection (Pn418) settings. For details, refer to "A-1 Parameter List" (P.A-1).
CX-Drive Data Tracing Function
Commands to the motor and motor operation (speed, torque command, and position error) can
be displayed on a computer as waveforms. Refer to the CX-Drive Operation Manual
(Cat.No.W453).
USB communications cable
Connect to CN7.
