7.6.7 Electrical Installation, Control Cables
Illustration 7.34: Diagram showing all electrical terminals without options.
A = analog, D = digital
Terminal 37 is used for Safe Stop. For instructions on Safe Stop installation please refer to the section
Safe Stop Installation
of the AF-650 GP Design
Guide.
* Only available on frequency converter with factory installed brake chopper.
** Factory installed option
Very long control cables and analogue signals may in rare cases and depending on installation result in 50/60 Hz earth loops due to noise from mains supply
cables.
If this occurs, it may be necessary to break the screen or insert a 100 nF capacitor between screen and chassis.
The digital and analogue inputs and outputs must be connected separately to the common inputs (terminal 20, 55, 39) of the frequency converter to avoid ground
currents from both groups to affect other groups. For example, switching on the digital input may disturb the analog input signal.
