3.2 Explanation of the pin assignment

3.2.1 Connector 1 (F48)

Integral switch-off The integral-action component of the speed controller

can be switched off at this input by injecting a high

signal (15 to 30V). This may be useful, e.g. for

positioning tasks. The motor does not drift slowly, but

has a lower holding moment.

During the normal operation, this input is inactive. The input is not to be wired

for this case or is to be connected to ground.

2b,

Positive Stop,

Negative Stop

A limit switch logic can be realized with these inputs.

For a running of the motor in positive direction the input

Pos.Stop is to be connected to +15V ... +30V. When

the connection is interrupted, e.g. by a limit switch

(nor

mally closed contact), the positive set values will be

suppressed and the motor is therefore braked with the

maximum adjusted pulse current. Negative speeds are

still possible. Simultaneously with the active stop

function the integral-action component is being

switched off. The same applies for the Neg.Stop input,

but for the negative rotational direction.

When these inputs are not used, they have to be connected to +15V.

4z GND-REF Reference ground for measuring the conditioned

tachometer voltage. Avoid external connection with

GND or Power-GND of the device, not via protective

earth terminal either (ground loops).

4b,

Set value+;

Set value-

Inputs of a differential amplifier to define the speed set

value. Terminal 4d has a positive effect against 4b.

The maximum differential voltage must not exceed

±10V. Always both inputs have to be wired, e.g. set

value + at the output of the D/A converter and set value-

at the output of the analogue GND of the D/A converter.

6z +5V Output of a +5V power supply, carrying

capacity+10mA.

Ready for operation

Potential-free Reed contact to indicate the ready-for-

operation status of the device. The contact is closed

when the device is ready for operation.

Maximum voltage 100V for 100mA.
