3.4 Connection Specifications
The actual connection will depend on the overall configuration of your drive system and the type of
motor you will be using. Follow the description in given order and choose the wiring diagram (as of
page 5-79) that best suits the components you are using.
How to read the following data
The following tables feature, where applicable, connection details for both versions the Module and the
Compact. Thereby,...
• the column «Module Header Pin» refers to the header's pin number.
Example: A23...A29 means header A, pins 23 thru 29
• the column «Compact/CB Connector Pin» refers to the connector's pin number.
Example: X1/X2 | 2 means connector X1/X2, pin 2
For easier legibility, the subsequently used circuit diagrams refer to the Module. For the corresponding
Compact's circuitry take the second column «Compact/CB Connector Pin» into account.
3.4.1
Basically, any power supply may be used provided that it meets the below stated minimum require-
ments.
Module
Header Pin
A23...A29**
A30...A36**
** Connect all pins in respect to the individual pin current rating.

Depending on load
• continuous max. 1.5 A
• short-time (acceleration, <30 s) max. 4.5 A
Use the formula below to calculate the required voltage under load.
Choose a power supply according to the calculated voltage. Thereby consider:
a) During braking of the load, the power supply must be capable of buffering the recovered
kinetic energy (for example, in a capacitor).
b) If you are using an electronically stabilized power supply, make sure that the overcurrent
protection circuit is configured inoperative within the operating range.
