Note
•
To prevent a repeat fault trip from occurring, set CON-71 (speed search options) bit 2 the same as
bit 1. The inverter will perform a speed search at the beginning of the operation.
•
If the speed search is not enabled, the inverter will start its operation in a normal V/F pattern and
accelerate the motor. If the inverter has been turned on without ‘reset and restart’ enabled, the
terminal block command must be first turned off, and then turned on again to begin the
inverter’s operation.
4.10 Setting Acceleration and Deceleration Times
4.10.1 Acc/Dec Time Based on Maximum Frequency
Acc/Dec time values can be set based on maximum frequency, not on inverter operation
frequency. To set Acc/Dec time values based on maximum frequency, set BAS- 08 (Acc/Dec
reference) in the Basic group to ‘0 (Max Freq)’.
Acceleration time set at DRV-03 (Acceleration time) refers to the time required for the inverter to
reach the maximum frequency from a stopped (0 Hz) state. Likewise, the value set at the DRV-04
(Deceleration time) refers to the time required to return to a stopped state (0 Hz) from the
maximum frequency.

Use caution when operating the inverter with Power-on Run enabled as the motor will begin
rotating when the inverter starts up.
