 Process PID has three types of correction mode: reference frequency correction prior to accel/decel,
reference frequency correction after accel/decel, and torque correction. These correction modes make it
convenient to use the inverter in master-slave synchronous control and tension control.
Reference frequency correction prior to accel/decel: PID output is added to the reference frequency
prior to accel/decel.
Reference frequency correction after accel/decel: PID output is added to the reference frequency after
accel/decel. Unlike the previous correction mode, this mode can also perform the correction during
accel/decel.
Torque correction: PID output is added to the reference torque. This correction mode is only valid for
torque control. As this correction mode has the fastest response, it can be used for synchronous control of a
rigidly-connected system.

Free PID function: PID acts as a programmable module. Its input and output can be defined
separately. PID output can be connected to the analog output.
For position control, process PID can be used as an annular position regulator. Refer to Page 96 for
the operation of process PID or frequency correction method.
