Acceleration/Deceleration Pattern - Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual

• The droop control and the speed loop integration at the emergency stop by the Emergency stop (X92) signal can be
enabled/disabled using Pr.1349 Emergency stop operation selection.

NOTE
• The X92 signals can be assigned to an input terminal by setting Pr.178 to Pr.189 (Input terminal function selection).
Changing the terminal assignment may affect other functions. Set parameters after confirming the function of each terminal.

Acceleration/deceleration pattern

The acceleration/deceleration pattern can be set according to the application.
In addition, the backlash measures that stop acceleration/deceleration by the frequency or time set with parameters at
acceleration/deceleration can be set.
