CHAPTER 4 - PARAMETER DESCRIPTION
4.1 Drive Group [DRV]
DRV-00: Output Frequency
This code gives information regarding motor
direction set in DRV-13, and output or reference
frequency.
You can set the command frequency by pressing
[FUNC] key in this code.
DRV-01: Acceleration Time
DRV-02: Deceleration Time
The inverter targets the FU2-70 [Ref. Freq. for
Accel/Decel] 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 [Maximum Frequency]
from 0 Hz. The deceleration time is the time taken
by the motor to reach 0 Hz from FU1-20.
When the FU2-70 is set to ‘Delta Frequency’, the
acceleration and deceleration time is the 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.
