DRV-02: Deceleration Time
The inverter targets the FU2-70 when accelerating or
decelerating. When the FU2-70 is set to “Maximum
Frequency”, the acceleration time is the time taken by the
motor to reach FU1-20 from 0 Hz. The deceleration time is
the time taken by the motor to reach 0 Hz from FU1-20
[Maximum Frequency].
When the FU2-70 is set to ‘Delta Frequency’, the
acceleration and deceleration time is the time taken to
reach a targeted frequency (instead the maximum
frequency) from a frequency.
The acceleration and deceleration time can be changed to
a preset transient time via multi-function inputs. By setting
the multi-function inputs (P1, P2, P3) to ‘XCEL-L’, ‘XCEL-
M’, ‘XCEL-H’ respectively, the Accel and Decel time set in
I/O-25 to I/O-38 are applied according to the binary inputs
of the P1, P2, P3.
➨ Note:
I/O-12 to I/O-14: Sets the terminal function of P1, P2,
P3 terminal inputs.
