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.
