Desired speed levels for multi-step control mode are selected with following parameters
Speed Parameter Input
Speed 1 P2.2.8. / P2.2.9. S1/ S2
Speed 2 P2.1.7. MS 2
Speed 3 P2.1.8. MS 3
Speed 4 P2.1.9. MS 4
1.6.1 Description of the control methods
EP-control requires two 2-step pushbuttons, one for
each direction. The operation is as follows:
- the rest position means standstill (0-position)
- during run the rest position means deceleration
- step one (switch S1 or S2) means hold speed
- when starting, step one means acceleration up to the minimum speed
- step two (switch AP) means acceleration (up to the maximum speed if
desired)
- at the maximum speed step two means hold speed, because the
maximum speed cannot be exceeded

rest = deceleration
step 1 = hold speed

EP3-control requires a 3-step controller. The
operation is as follows:
- the rest position means standstill (0-position)
- step one (switch S1 or S2) is the minimum speed command
- step two (EP hold command) means hold speed
- step three (switch AP) means acceleration (up to the maximum speed
if desired)
- when releasing the controller, step one means deceleration down to
the minimum speed

MS-control requires a 2 to 4-step controller. The
operation is as follows:
- each step has its own frequency
- the frequencies are freely selectable
-
when controller is set to a certain step, the speed changes to equal
value

1.7 Mechanical brake control
D2L has a brake contactor to control electromechanical disk brake of hoisting motor. The disk brake is opened
and kept open during run by DC-voltage. When there is no voltage present the brake is closed and also kept
closed by spring force.
The brake is controlled so that during starting the motor first generates torque and after that the brake is
opened. The same applies for stopping; while the brake is being closed, the motor still generates torque.
