Normal Operation
Temperatures
If the surface temperature of the winch exceeds 90°C (194°F) there is a risk of
damaging the winch.
Duty cycle
The winch should not be operated at a duty cycle higher than 30% for longer periods of
time.
Lifting speeds and weight
The load of the winch impacts the minimum speed it can operate at. At high loads the
minimum speed up must be increased to a point where the winch can still move.
If a lower load is used with high minimum speeds the winch might have problems with
finding its position. Lower the minimum speeds if this is a problem.
The minimum speed can be adjusted from the menu.
Wire fleet
Because of the way the winch rolls up the wire the place where the wire comes out of
the winch changes depending on how much wire has been rolled out. The wire moves
535 mm sideways from the top position to the bottom position during the movement.
Synchronized movements of multiple winches
If several winches are installed to perform synchronized movements the best result is
achieved by using a fading 16 bit position. By nature there is a slight deviation in
performance of the motors so some motors have a slightly higher maximum speed than
others.
Like when fading light, the positions of the different winches should be faded, and the
winches will tend to follow that fade. When fading the positions:
1.
The speed channel should be a set to 100 to gain the highest possible speed.
2.
The position channel should be added as a 16 bit channel and not just the MSB
on channel 1.
3.
The speed of the fade needs to be slower than the maximum speed, so the
motors have speed enough to perform the movement.
If the fade of the positions is too fast, the winches will move at the maximum speed,
and you will see the difference in the motor speed.
If the fade is to slow the winches will move – stop – move – stop, when the position
changes, thus giving a discontinuous movement.
