Wegner Crane CFW500 series Applications Manual - page 28
Parameters Description
Crane | 28
Description:
This parameter defines the period without hoisting/forward or lowering/reverse commands that has to elapse
before the inverter general enable command is removed, thus demagnetizing the motor. This measure prevents
the motor from remaining energized during a period while the crane motion is not being used.
NOTE!
Keeping the motor magnetized in the absence of hoisting/forward or lowering/reverse commands
allows a faster motor response when those commands are issued, expediting its operation.
3.2 RAMPS
This parameter group allows the user to configure the inverter ramps, so that the motor is accelerated or
decelerated in a faster or in a slower manner
.
P0100 – Deceleration Time
Adjustable
0.0 to 999.0 s
Factory Setting: 3.0 s
Range:
Proprieties:
Access groups via HMI:
BASIC
Description:
This parameter defines the time to accelerate lineally from 0 to the maximum speed (defined in P0134).
P0101 – Deceleration Time
Adjustable
0.0 to 999.0 s
Factory Setting: 2.0 s
Range:
Proprieties:
Access groups via HMI:
BASIC
Description:
This parameter defines the time to decelerate linearly from the maximum speed (defined at P0134) to zero,
except in case of an emergency stop command execution.
P0103 – Emergency Stop Time (2nd Ramp Deceleration)
Adjustable
0.0 to 999.0 s
Factory Setting: 0.3 s
Range:
Proprieties:
Access groups via HMI:
BASIC
Description:
This parameter defines the time to decelerate linearly from the maximum speed (defined at P0134) to zero,
when an emergency stop command via the digital input DI3, the limit switch "Stop Hoisting ", the overweight
(vertical), the momentary overload (horizontal), detection or the slack cable detection (vertical), is executed.
P0104 – S Ramp
Adjustable
0 = Linear
Factory Setting: 0
Range:
1 = S Curve
Proprieties:
Access groups via HMI:
BASIC
Description:
This parameter allows that the acceleration and deceleration ramps have a nonlinear profile, similar to an “S”
shape curve.
The “S” ramp reduces mechanical stress during accelerations and decelerations.
