PM330 Power Modules
■
Overview
PM330 Power Module, degree of protection IP20, frame size GX
PM330 Power Modules have been specially developed for
simple applications, such as driving pumps, fans and compres-
sors with speed-controlled increasing load characteristics.
PM330 Power Modules meet the very high energy efficiency
requirements particularly well, especially in this area of applica-
tion, because they offer the best possible energy utilization in all
operating ranges. This is achieved by the very high efficiency
verified according to EN 50598, various energy-saving func-
tions, and the automatic pulse frequency adjustment.
To reduce emissions, the PM330 Power Modules are equipped
with a radio interference suppression filter as standard (in accor-
dance with the limit values defined in Category C3). Through the
use of an external line filter, the PM330 Power Modules also com-
ply with the limits for use in the first environment (Category C2)
as specified in EN 61800-3

.
If required, various high-performance dv/dt filters or a Braking
Module can be connected. A corresponding DC link connection
is available as standard.
All available system components are coordinated exactly with
the PM330 Power Modules. This enables the implementation of
reliable, safe, customized control cabinet solutions. All connec-
tions can easily be accessed from the front. The internal
modules are very easily accessible.
Exceptional requirements concerning motor cable lengths can
be easily implemented via output reactors. Series connections
are permissible here.
The PM330 Power Modules are designed for connection to
grounded TN/TT systems and non-grounded IT systems. 690 V
line supplies with grounded line conductor are not permitted.
The CU230P-2 Control Unit intended for PM330 Power Modules
does not have special Safety Integrated functions. Safety
functions can be implemented by means of external switching
devices.
■
Integration
The PM330 Power Modules have the following connections and
interfaces:
•
PM-IF interface to connect the PM330 Power Module to the
Control Unit. The PM330
Power Module also supplies power to
the Control Unit using an integrated power supply.
•
Motor connection and line supply connection via screw studs
•
DC-link connection for Braking Module and dv/dt filter
•
PE (protective earth) connections
•
Terminal block X9
- Input for external 24 V DC supply
- Input for external alarm/fault
- Input for EMERGENCY OFF / EMERGENCY STOP
- Output for DC 24 V (Output current max. 250 mA)
- Control of the main contactor
- Feedback message "DC link charged"
•
Terminal block X41
2)
- Two-channel STO control
- Switch-off signal path feedback
- Enabling STO via combination on switch S41
PM330 Power Modules communicate with the Control Unit via
the PM-IF interface.
For the STO and SS1 safety functions, we recommend the use of
SIRIUS 3SK1 safety relays with relay outputs and 24 V supply
voltage. The safety relays can be directly supplied with voltage
by the Power Module. This enables the very simple implementa-
tion of the STO safety function.

STO: 3SK1111-2AB30
•
SS1: 3SK1121-2CB42

Modules PM330 Hardware Installation Manual.
Connection diagram for PM330 Power Module
1)
To comply with Category C2, shielded cables must also be used between
the converter and motor with a maximum permissible cable length of
150 m (492 ft). Long cables can be used if output reactors and output
filters are connected
(see section Load-side power components)
.

The Safety functions are available from functional status FS 04 of the
Power Modules.
