Min.:
0.0
Unit:
s
Max.: 100.0 Data type: UInt16
Default:
0.0
Change:
At stop
Value Range:
0.0s to 100.0s
Description
This parameter defines the hold time during which the output frequency remains at the startup
frequency. After this hold time elapses, the AC drive will accelerate to the reference frequency.
F6-05
DC braking current/Pre-excitation current at startup
Address:
62981
Min.:
0
Unit:
%
Max.: 100 Data type: UInt16
Default:
0
Change:
At stop
Value Range:
0% to 100%
Description
When startup with DC braking is enabled, the AC drive starts only after DC braking upon receiving the
start command. A greater DC braking current indicates greater braking force. 100% corresponds to
the rated motor current (the upper limit of the current is 80% of the rated current of the AC drive).
The current upper limit can be set through F6-34, and the maximum upper limit allowed is 135% of
the rated current of the AC drive.
F6-06
DC braking time/pre-excitation time at startup
Address:
62982
Min.:
0.0
Unit:
s
Max.: 100.0 Data type: UInt16
Default:
0.0
Change:
At stop
Value Range:
0.0s to 100.0s
Description
This parameter defines the time for DC braking at startup, which is valid only when the startup mode
is direct start.
F6-07
Acceleration/Deceleration mode
Address:
62983
Min.:
0
Unit:
-
Max.: 2 Data type: UInt16
Default:
0
Change:
At stop
Value Range:
0: Linear acceleration/deceleration
1: S-curve acceleration/deceleration
2: Four-segment S-curve acceleration/deceleration
Description
This parameter defines the frequency change mode during the AC drive start and stop process.
0: The output frequency increases or decreases linearly.
1: When the target frequency changes dynamically in real time, the output frequency increases or
decreases based on the S-curve. This mode is applicable to applications requiring supreme comfort
and quick response in real time.
2: On the basis of 1, the start and end sections of acceleration and deceleration of the S-curve can be
set by F6-26 to F6-29.
