P4.1.6
b
Power up local remote select
ID 1685
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Hold last;
1 = Local control; or
2 = Remote control.
Description:
Selects what control place the drive will start at after power is applied. The default setting will hold the last state that the drive was in
when powered down, selecting Local or Remote will cause the drive to start in that mode regardless of last state.
P4.1.8
b
Start mode
ID 252
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Ramp - The drive starts from 0 Hz and ramps to the frequency reference value.
1 = Flying start from stop frequency - The drive will catch a spinning motor. This setting searches for the current frequency using the
last operating frequency as a starting point.
2 = Flying start from maximum frequency - The drive will catch a spinning motor. This setting searches for the current frequency using
the maximum operating frequency as a starting point.
Description:
Selects the start mode operation.
P4.1.9
b
Stop mode
ID 253
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
1
Options:
0 = Coasting - After a stop command, the motor coasts to a stop uncontrolled by the drive.
1 = Ramp - After the stop command, the speed of the motor is decelerated according to the set deceleration parameters.
Description:
Selects the stop mode operation.
P4.1.10
b
Ramp 1 shape
ID 247
Minimum value:
0.0 s
Maximum value:
10.0 s
Default value:
0.0 s
Description:
The start and end of the acceleration and deceleration ramps can be smoothed with these parameters. Setting a value of 0.00 seconds
gives a linear ramp shape that causes acceleration and deceleration to react immediately to the changes in the reference signal.
Setting a value from 0.10 to 10.00 seconds for this parameter produces an S-shaped acceleration/deceleration at the start and stop of
the slope.
