Quick Setup
VEM motors Thurm GmbH Compact Drives Series M21 ... T
10/2005 1
The present Quick Setup enables the user to install the Compact Drive step by step and to drive
the motor in the factory settings. This Quick Setup is handled with every drive.
Complete statements and advices to our product conception and the choice of drive as well as
complete technical data papers and listing of parameters with detailed descriptions of parameter
setup and a presentation of possible serial communication is contained in the Design Guide which
is handled with every Local Control Panel (LCP2).
NB! Please read carefully the safety regulations and the installation instructions
in the Operating Manual or the Design Guide before putting into operation the
Compact Drive. Look at www.vem-group.com / products / drive solutions.
1. Electrical Installation
1.1. Mains terminals
Remove the inverter box cover, which is held by four screws, to obtain access to the terminals.
Remove the detachable terminal plugs from the terminal blocks X100 (4-pole) and X101 (9-pole) to
obtain access to the mains terminals (see fig. 1).
To contact the mains terminals L1, L2 and L3
lift only the corners of the black plastic cover!
Fig. 1
NB!
Before connecting the mains terminals L1, L2, L3 be aware that the mains supply is
identical with the voltage on the name plate of the Compact Drive

You may use unshielded cable for connecting the mains terminals. The phases of the mains supply
and the earth have to connect to the referring terminals. Cable inlet have to put through one of the
3 cable glands.
Sizes of cable glands: P = 0,55 up to 3 kW: 3 x M20x1.5;
P = 4 up to 7,5 kW: 2 x M20x1.5; 1 x M25x1.5
Tightening torques: L1, L2, L3: 0,55 up to 4 kW: 0,5 ... 0,6 Nm
5 up to 7,5 kW: 1,2 ... 1,5 Nm
Earth Screw (at any powers): 3,4 Nm
Cover screws (at any powers ): 2,2 ... 2,4 Nm
Prefuses max.: P = 0,55 up to 3 kW: 16 A
P = 4 up to 7,5 kW: 25 A
Protecting equipment: Use ELCB relays of type B with leakage currents of 100mA
(ELCB relays of type A are not allowed for direct current content (DC)
in the fault current and power-up with short charging current to earth)
1.2. Terminals for data communication and control signals
Communication to the Compact Drive is realized via terminal block X100. Drive control is possible
via terminal block X101.
For information on terminal blocks X100 and X101, please see table A and B.

RS 485 switch
For terminating an RS 485 interface serial communication, the bus must be terminated by a
resistor network at both ends. This is provided by setting both switches to ON.
LEDs
The Compact Drive has five LEDs which indicate the status of the Compact Drive:
LED 300 red Fault trip
LED 301 yellow Warning
LED 302 green Power on
LED 303-304 green Communication
EMC-correct installation
The control cables must be screened cables to ensure EMC-correct electrical installation.
Connect the screen to earth at both ends.
Avoid installation with twisted screen ends (pigtails), since this ruins the screening effect at high
frequencies. Use cable clamps instead.
2. Start the Compact Drive
Figure 2 shows the factory settings of terminal block X101 for starting the VEM Compact Drives
without any additionally accessories for local or remote control.
The steps of starting have to be kept!
Fig. 2
* also usable as digital input (see Table B) ** also usable as digital output (see Table B)
• Open the lid of the FC by releasing the screws
• Install RESET pushbutton between terminals 3 and 6 to clear any trip
• Connect switch START between terminals 4 and 6 to start the drive clockwise or switch
START + REVERSING between terminals 5 and 6 to start the drive counterclockwise
(in factory setting terminals 4 and 6 are bridged by a cable to start the drive clockwise at
power-up with a speed refering to the reference at terminal 2)
• Connect terminal 2, 7 and 8 to the potentiometer (see fig. 2).
• Connect mains terminals L1, L2, L3 and earth terminal. Switch on mains supply.
NB ! The voltage on the Compact Drive is dangerous when the motor is connected
to mains. Incorrect installation of the Compact Drive may lead to material damage or
serious injury or it may be fatal.

• Press START if there is a switch installed instead of the factory set bridge to start the
drive in clockwise rotation or press START + REVERSING to start the drive in
counterclockwise rotation.
• Set reference to analog input:
- Use internal reference 10 V DC and a potentiometer (see fig. 2); or
- Connect external reference 0 ... 10 V to terminal 2 . Use common (0 V) of terminal
8; or
- Set current 0 ... or 4 ... 20 mA of an external current source to terminal 1 against
common (terminal 8)
Enable terminal 1 by set-up parameter 331 and scaling via parameters 336 and 337
by means of LCP2 or PC programming software
What if the motor does not start?
o Make sure no parameters have been changed from initial delivery status (factory
setting). Use the Local Control Panel or serial port to reset to factory setting.
o Make sure no [STOP]-command have been issued by the optional control panel
keyboard (local stop). Control Panel [STOP] can only be restarted by the Control
Panel [START]- button!
o Remove lid to check the Light Emitting Diodes visible through a hole in the
inside isolation cover, follow Table below.

The manual “Installation, operating and maintenance instructions Three phase
asynchronous motors with squirrel cage rotor and slip ring rotor, standard design”, ID-No.
VEM 68 238 01, is generally valid for Compact Drives, too. Please note that the indicated
number of service hours is only valid for operation at the rated speed. If during operation
of the motor the nominal speed is exeeded then the regreasing period reduces
approximately in the opposite ratio to the increase in the motor speed.
No. of switches of the mains: max. 1 every 2 minutes
Environmental temperature: -10°C (at reduced load) … +40°C
Environmental conditions: no direct exposure to sunlight because of overheating
