Synchronization If required, two or more D2H or D2C can be driven in precise
synchronization. A separate synchronization controller is needed for this.
The same speed reference (in EP- or PO-mode) is connected to every
D2H or D2C and the correction signal for synchronization is connected
to all D2H or D2C to input AIN2+. The speed reference signal of each
D2H or D2C can also be modified separately by a PLC. Synchronization
is activated by parameter selection.
1.7 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

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

PO-control requires a controller with potentiometer.
The operation is as follows:
− when the controller is at the rest position the
potentiometer is at the middle position causing
zero speed
− run commands are controlled separately by
closing the direction switches (S1 and S2)
− when the operator turns the controller to any
direction, the speed increases
− the same turning angle of the controller causes a
smaller change in speed, the closer the speed is
to the minimum speed
AU-control requires an analog reference from radio
or PLC. The operation is as follows:
− the speed linearly follows the input signal. 0V
means zero speed and the higher the voltage, the
