For multi-axis systems, observe the specific operating conditions for your system.
To reach the max. permitted cable length, observe cable requirements ð p. 35.
* Danaher Motion North America supplies cables up to 39 meters
* Danaher Motion Europe supplies cables up to max. length
6.5 LED display
A 3-character LED display indicates the status of the amplifier after switching on the 24V
supply (ð p.79). When the keys on the front panel are used, the parameter and function
numbers are shown, as well as the numbers for any errors that may occur (ð p.80).
