1.6 Control

methods

There are four different control methods (command modes) available. All of them are available without
any changes in the hardware or software. Any single D2H or D2C can be controlled either by a
pushbutton controller in EP-mode, by a joystick type controller with a potentiometer located in the cabin
in PO-mode or by a process computer in AU-mode. The only external device needed is a switch to
select the desired control method.

EP Electronic motor potentiometer function.

− Stepless control using a 2-step pushbutton controller.

− EP3 stepless control using a 3-step controller.

P
O

Potentiometer control using a joystick type controller.
− Requires a single 15V power supply (included in D2H/D2C).

− Any additional amplifier is not needed.

AU Automation

control

− For any control device with an output in the range of 0-10V.

− E.g. radio-controls, process computers.

M
S

Multistep control (2-4 steps as standard).
− Requires programmable digital inputs for speed reference steps

(included in D2H/D2C).

Command mode
selection

The command mode (EP, PO or AU) is selected by the switches CMS
and AP. Normally the selection can be done only when the motion is
stopped (not when running), but in special applications changing the
mode is allowed during run by changing parameter values.

PO- and AU-modes

PO- and AU-modes select either of the analog inputs for speed
reference. Both analog inputs can be adjusted similar from 0V to 10V
(radio or PLC-reference) or from 10V to 6.7V (potentiometer). As default,
Ain1 is used in PO-mode and Ain2 is used in AU-mode.

EP-mode

EP-mode selects the AP-button for speed reference. EP step 1 is
command for minimum speed or hold speed. EP step 2 is the
acceleration command.
