Smooth pole-change unit WPU
1 Description
Smooth pole-change units WPU optimize the operational performance of pole-changing motors
for applications where smooth changing from high to low speed is required.
The regenerative brake torque when switching from high to low speed can – depending on the
design and f ram e s iz e of t he m ot or – for a sh or t t ime re ac h th r ee to n ine ti me s th e ra ted t orq ue of
the low-speed winding.
The smooth pole-change unit WPU reduces this regenerative change-back torque to approx. one
third of the above mentioned values.
When the change-back braking process is initiated, the integrated electronic circuit, using a wearfree switching element (Triac), opens one phase of the motor power supply.
The breakaway and rated torques of the motor are not effected by this at all.
Smooth pole-change units WPU 1001/1003 and 1010 are designed as modular units for top-hat
rail mounting with screw terminals.
Units WPU 1001 and 1003 come without heatsink; WPU 1010 is provided with a heatsink,
mounted on the side of the housing.
WPU 2030 is designed for switch ca bi net installation. This unit has a heatsink integrate d i n the rear
of the housing.
Characteristics:
• precise, automatic reconnection of the third phase after change-back – current-and speed-opti-
mized in the synchronous point – completely load-independent
• no loss of energy, high efficiency
• wear-free
• full starti ng torque
• unlimited starting frequency
• minimal wiring requirements
• suitable for use with any pole-changing motor

When installing the unit, please observe the following mechanical and electrical requirements:
• Important: Ensure that the unit is sufficiently cooled!
• Ensure protective earthing of WPU 1010 and WPU 2030.
• The lead cross-sections are to be dimensioned depending on the motor connected.
Maximum lead cross-section: WPU 1001/WPU 1003/WPU 1010: max. 2.5 mm
2
WPU 2030: max. 16 mm

• The fuses are to be chosen in accordance with the lead cross-section and the connected motor.
As overload protection for the WPU, a motor circuit-breaker with instantaneous magnetic
tripping may be used. It is to be interconnected in the lead of the low-speed winding and to be
adjusted to the rated current of this winding (please refer to page “Technical Data”)
The unit is to be installed by qualified electrical personnel only, in strict compliance with the
applicable regulations for the prevention of accidents and the installation and operating
instructions!

3 Commissioning
It is recommended to carry out the commissioning with the motor in the cold state.
1. Switch the motor off.
Take appropriate measures to prevent unintentional switch-on of the motor!
2. For hoists and brake motors:
Ensure that the brake is disconnected electrically, i. e. that the brake is applied.
For this pur pose, remove the lead at te rminal 2 and/or terminal 3 o f the brake rectifier.
3. Turn the potentiometer 20 turns in counterclockwise direction (I
min
).
Note: The 20-turn potentiometer is provided with a slipping clutch, so no stop can be felt.
4. Connect the motor at low speed.
→ The red LED lights up.
The motor does not rotate.
5. Turn the potentiometer in clockwise direction
→ The red LED goes off.
Motors without brake: The motor starts rotating.
Brake motors: The moto r wants to start rotating, how ever, is blocked by the
brake and therefore needs to be switched off as soon as
possible.
Leave potentiometer setting at this point.
6. Switch the motor off again.
7. For brake motors with disconnected brake:
Reconnect brake.
8. Carry out trial run.
The setting is correct if
• the motor starts rotating immediately when connected (at low speed), the red LED does not
shine.
• and
the red LED lights up when cha nging from hi gh to l ow speed. Th e LED remai ns lit du ring t he
deceleration process thus indicating its duration.
The setting is incorrect if
• the motor does not start rotating immediately when connected (at low speed), the red LED
shines.
→ Turn potentiometer in clockwise direction.
• the red LED does not light up when changing from high to low speed.
→ Turn potentiometer in counterclockwise direction.
The unit is to be installed by qualified electrical personnel only, in strict compliance with the
applicable regulations for the prevention of accidents and the installation and operating
instructions!
