List of Parameters

Sets the baud rate for RS-232 communications.

Do not change.

Sets the position loop responsiveness.

Increasing the gain increases position control responsiveness and

shortens stabilization time.

Oscillation or overshoot will occur if set too high. Adjust for opti-

mum responsiveness.

Sets the speed loop responsiveness.

If the Inertia Ratio (Pn020) is set correctly, this parameter is set to

the Servomotor response frequency.

Increasing the gain increases the speed control responsiveness,

but too much gain may cause oscillating.

Small gain may cause overshoot in the speed response.

Adjust for optimum responsiveness.

Adjusts the speed loop integration time constant.

Set a large value for large load inertia.

Decrease the setting for fast response with small inertia.

Set 9999 to stop integration operation while retaining the integra-

tion value. A setting of 10000 disables integration.

Sets the type of speed detection filter time constant.

Normally, use a setting of 0.

Increasing the value reduces the noise of the Servomotor but also

reduces its responsiveness.

This parameter is disabled if the Instantaneous Speed Observer

Setting (Pn027) is enabled.

Adjusts the first-order lag filter time constant for the torque com-

mand section.

The torque filter setting may reduce machine vibration.

Sets the speed feed-forward amount.

This parameter is particularly useful when fast response is

Sets the time constant for the speed feed-forward first-order lag fil-

Do not change.
