- There are three different sizes of motors and drives. All control units

run a 3-phase stepper motor. All control units have an input signal of

0-10 V.

- The drives have a built-in linerarization of the input signal, which

means that the rotor’s efficiency is proportional to the input signal.

- The drives have a preset threshold value of 0.1 V (hysteresis 0.13–0.07 V).

If the input signal falls below this value, the rotor stops.

- The drives have a rotation monitor (magnet mounted on the rotor with

associated magnetic sensor) and built-in cleaning function.

The functions can be disabled via DIP switches.

- The drives restart automatically after a voltage dip and

reset all alarms on restart.

- The motors are stepper motors and have the same torque over the

entire speed range.

- To avoid windmilling, a holding torque is applied when the motor is

stationary.

- The motor is equipped with a 2 m cable as standard.

- If total cable length exceeds 3 m, external EMC filters should be used.

Rotation

monitor

The rotation monitor is activated if a pulse is not received

every 30 minutes at min. rotation speed and every 20

seconds at max. rotation speed. The time between these

speeds is linear. The function can be disconnected using

DIP switches.

Probable

fault cause

installation

- Magnet turned the wrong way.

- Magnet transmitter connected incorrectly

(wrong polarity), see CONNECTIONS on page 4.

- The gap between the magnet transmitter

and the magnet is too large max. 15 mm.

Probable

fault cause

in operation

- The belt is broken.

- The belt is slipping.

- The rotor is stuck or too heavy.

- The magnet transmitter or magnet is broken.

Motor

temperature

The motor temperature indicator is activated if the coil

temperature in the motor is too high. The thermal contact

in the motor returns to normal when the temperature

drops.

Overvoltage The Overvoltage indicator is activated if the input voltage

exceeds 265 V.

Undervoltage The Undervoltage indicator is activated if the input

voltage falls below 190 V.

Over/under

temperature

The Over/under temperature indicator is activated if the

temperature in the control unit exceeds temperature

span -30 °C - +85 °C.

Short circuit The Short circuit indicator is activated and alarms if the

event of short circuit phase-phase or phase-earth.

Probable

fault cause

- Short circuit between phases in cable or motor.

- Short circuit between phase-earth in cable or motor.

- Cable break to one phase.

Measure motor resistance; it should be identical on all coils.

Internal fault The Internal fault indicator is activated if an internal fault

in the control system has occurred.

DIP SWITCHES

OPERATIONAL INDICATIONS

*) Manual running (test mode)

Cleaning The Purging function is activated when in ON position.

Every 10 minutes the motor rotates first 6 s at 5 rpm

and then another 10 to 20 s (randomized) at 20 rpm.

Rotation monitor Rotation monitor activated in ON position.

High speed *) The motor rotates at the set max. rpm when the

switch is set to ON.

Low speed *) The motor rotates at the preset min. speed (1 rpm)

when the switch is set to ON.

On/Alarm "Fixed green light when powered on. Flashes when the

control unit has tripped.

Run Lit when the motor is going to rotate, that is, when the

input signal exceeds the threshold value.

Rotation Flashes when the magnet passes the magnetic sensor,

regardless of DIP switch settings and input signal value.

ALARMS

In the event of an alarm, the respective red alarm LED is turned on for 30

seconds. After the restart the LED is turned off.

This sequence is repeated twice if the fault remains. After a third time

the system enters error mode and the alarm relay is activated. All three

alarm events must be activated within 90 minutes to activate error mode.

The green LED is fixed during the first and second alarm and flashes

during the third. All alarms are latched subsequently.

which means that input signal and rotation speed are as shown in the

adjoining diagram.

VERIFICATIONS BEFORE SWITCHING ON THE CONTROL UNIT

COMMISSIONING

Verify that

the drive is connected according to instructions on page 9.

Input voltage 230 VAC +/-15%, 50/60 Hz.

Verify that the input signal is 0-10 V.

Verify that rotation monitor and cleaning function are connected.

Verify that the motor rotates in the desired direction. If

erroneous direction, switch two motor phases.

Adjustment of

max. speed

Set “High Speed” DIP switch to ON. Adjust the

“Max. speed” until the rotor rotates at the desired

speed.

Verifying minimum

speed

Set “Low Speed” DIP switch to ON. Ensure that the

rotor starts to rotate. The min. speed is preset.

Verifying the

purging function

Turn off the main power. Ensure that the “Cleaning”

DIP switch is set to ON and that the input signal is

disconnected. After turning on the power, the rotor

rotates for 20 seconds at 12 rpm.

Controlling the

rotation monitor

The yellow “Rotation” light diode should flash

when the magnet passes the magnetic sensor,

regardless the DIP switch position.

Finalize the test by rotating the rotor at max. and min. rotation speed
