7-5 Manual Tuning
Basic Settings
As described before, the OMNUC G-Series Servo Drives have an autotuning function. Depending
on load conditions or other restrictions, however, readjustment may be required if the gain cannot
be properly adjusted when autotuning is performed or the optimum responsiveness or stability is
required to match each load. This section describes how to perform manual tuning for each control
mode and function.
Before Manual Setting
The front panel or the Parameter Unit can be used to adjust the Servomotor (machine) while
monitoring the operation or noise, but 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 Servomotor speed, command speed, torque, and number of accumulated pulses can be
measured in the analog voltage level using an oscilloscope or other device. Set the type of signal
to be output and the output voltage level by setting the SP Selection (Pn07) and IM Selection
(Pn08). For details, refer to Control I/O Connector Specifications (CN1) on page 3-9 and Parameter
Tables on page 5-33.
CX-Drive Data Tracing
Commands to the Servomotor and Servomotor operation (e.g., speed, torque commands, and
position deviation) can be displayed on a computer as waveforms. Refer to the CX-Drive Operation
Manual (Cat. No. W453).
