1 Basic Information
C1, C1f 3
Electronic equipment is not fault proof. This fact should be borne in mind for all
possible operating conditions.
Before installation or commissioning begins, this manual must be thoroughly read
and understood by the technical staff involved.
If any uncertainty arises, the manufacturer or dealer should be contacted.
P3 devices are power electric parts used for regulating energy flow.
Protection rating IP00.
Standards and guidelines
The device and its associated components can only be installed and switched
on where the local regulations and technical standards have been strictly
adhered to:
EU Guidelines 89/392/EWG, 84/528/EWG, 86/663/EWG, 72/23/EWG
EN60204, EN50178, EN60439-1, EN60146, EN61800-3
IEC/UL IEC364, IEC 664, UL508C, UL840
VDE Regulations VDE100, VDE110, VDE160
TÜV Regulations
Trade body guidelines VGB4
The user must ensure that in the event of:
- device failure
- incorrect operation
- loss of regulation or control
the axis will be safely de-activated.
It must also be ensured that the machine or equipment are fitted with device
independent monitoring and safety features.
Setting adjustments
- should only be carried out by suitably trained personnel
- should only be carried out in accordance with health and safety guidelines
Assembly
- should only be carried out when all voltages have been removed.
QS
Test results are archived with the device serial number by the manufacturer.
CE
The device adheres to the following: Guideline EU 89/336/EWG. EMC standards
EN61000-2 and EN61000-4.

- power: up to 720W
- tacho control
- armature voltage control with IxR compensation
- torque control
- cascade control speed/current
- rectangular current/speed characteristic curve
- switch on and switch off logic
- mains connection can directly be switched
Compact single-board device
- European format
- pluggable terminal connection (-W)
- C1: galvanic connection
- C1-4f: galvanic isolation of the control and the power section
- fully insulated power semi-conductor
- field rectifier
Note for C1 devices:
Direct mains connection
- zero connection >> on thyristor negative electrode potential
- all control connections >> on mains potential
- switches and poti >> isolation voltage > 1500V
Connection via an isolating transformer
- zero connection >> with potential isolation
- control connections >> to be earthed and shielded
Note for C1-4f devices:
Tacho control
- device >> with potential isolation
Armature voltage control
- control unit >> with a high impedance mains connection
- zero connection (terminal no. 5) must not be earthed
Build
- switch cabinet mounting according to the VDE, DIN and EU regulations
- standard control electronics REG
- intrinsically safe power section with current control loop
- optional units
Galvanic isolation between
- the power section and the housing
- the power section and the control electronics
The distance of air gaps and leakage paths adhere to the VDE standards (>8mm).
Components
- fully insulated thyristor modules, comfortably over-dimensioned
- only components customary in trade and industrially standardised are used
- high-quality bases for the IC with external connections
- LED displays
- DIP switches for the P-I adjustment of the current control loop
- precision potentiometers for fine adjustments
- plug-in jumpers for the system set-up
