(position

This is used to set the constant of a primary delay to the position command.
You can select a control method from "Primary delay" or "Linear
acceleration/deceleration" in [Pr. PB25 Function selection B-1]. The setting range of
"Linear acceleration/deceleration" is 0 ms to 10 ms. Setting of longer than 10 ms will
be recognized as 10 ms.
(Example) When a command is given from a synchronizing encoder, synchronous
operation will start smoothly even if it starts during line operation.

Feed forward
gain
Set the feed forward gain.
When the setting is 100%, the droop pulses during operation at constant speed are
nearly zero. However, sudden acceleration/deceleration will increase the
overshoot. As a guideline, when the feed forward gain setting is 100%, set 1 s or more
as the acceleration time constant up to the rated speed.
Setting range: 0 to 100

Load to motor
inertia
ratio/load to
motor mass
ratio
This is used to set the load to motor inertia ratio or load to motor mass ratio.
Setting a value considerably different from the actual load moment of inertia may
cause an unexpected operation such as an overshoot.
The setting of the parameter will be the automatic setting or manual setting depending
on the [Pr. PA08] setting. Refer to the following table for details. When the parameter
is automatic setting, the value will vary between 0.00 and 100.00.
Setting range: 0.00 to 300.00
