3.1.2 Acceleration and deceleration ramp
Acceleration and deceleration ramps are set by switch S3 as follows:
Switch S3 Ramp time (sec)
-1 -2 -3 -4
1 0 0 0 1.5
0 1 0 0 2.0
0 0 0 0 2.5
0 0 1 0 3.0
0 0 0 1 3.5
1 0 0 1 4.0
1 1 0 0 4.5
0 0 1 1 5.0
1 1 1 0 5.5
1 1 0 1 6.0
1 0 1 1 6.5
1 0 1 0 7.0
0 1 1 1 7.5
0 1 0 1 8.0
It is possible to reduce the deceleration ramp time by 30% if necessary. The fast deceleration ramp is activated by
switching S5-3 ON (1).
3.1.3 Example of parameter setting:
Acceleration/deceleration time of 3 seconds is selected by setting switch S3=0-0-1-0.
Fast deceleration (3sec is reduced to 2.1sec) is activated by switch S5-3=1.

3.2 Stopping method
The motor can be stopped either by dynamic braking (=by a ramp) or by mechanical brake. When stopping by
mechanical brake is selected and drive command is switched off the inverter immediately cuts off the motor current and
opens the relay contact. The stopping method is selected by switch S5-4 as follows:
S5-4 = 0 Stopping by a ramp
S5-4 = 1 Immediate stopping by mechanical brake
3.3 Control mode
There are four different control modes available. The inverter operation in different control modes is explained in section
4. The control mode is selected by switches S6-1 and S6-2 according to the table below.
Control mode S6-1 S6-2
MS2 0 0
EP2 1 0
EP3 0 1
MS4 1 1
The functions of all five digital inputs is assigned automatically according to the selected control mode:
