Detailed Parameter Description
No. Parameter
name
Description
Deceleration time
Used to determine the output frequency change ratio during deceleration.
•
Specify the time required for change by 50 Hz.
•
When this parameter is set to “0” seconds, the actual deceleration time
is 0.01 seconds.
•
For a set value less than 3 sec., the increment/decrement step is 0.01
sec. For a set value over 3 sec. to less than 10 sec., the step is 0.1
sec. For a set value over 10 sec., the step is 1 sec.
No.2 deceleration
time
The deceleration time can be set when [
I5 function selection] or
[
I6 function selection] is set to
(No. 2
acceleration/deceleration).
No.3 deceleration
time
No.4 deceleration
time
These deceleration times can be set when [
I5 Function selection]
and [
I6 Function selection] are both set to
No.2
acceleration/ deceleration.
Base frequency
Used to set the base frequency
(maximum frequency in
constant torque range)
between 30 and 400 Hz,
according to the motor’s rating.
Motor oscillation may occur
depending on the setting of this
parameter.
Maximum output
voltage
adjustment
Used to adjust the maximum
output voltage (base frequency
voltage).
The adjustment range is 0 to
100% of input voltage.
Used to specify proper V/F
characteristic according to load
characteristic.
■
Constant torque load
●
Reduced torque load
Fine adjustment between 1.0 and 2.0
is enabled.
V/F reduction
characteristic
Note) Enabled when [Torque control] is set to “manual boost” only. Motor
oscillation may occur depending on the setting of this parameter.
