Robot CPU (SQ series only)
The control units of the SQ series have an external CPU, which can be added to an already existing
SQ system.
Always make sure to connect the EMI line, otherwise the EMERGENCY-OFF state is always enabled.
The maximum permissible cable length is 30 m.
Lay the cable in a cable channel or fix the cable near to the CPU to ensure a secure connection
with plugs CN1 and CN2.
The catch is only used to simplify the installation process. Fix the CPU using the fixing screw on the rack.
Use an external battery as otherwise the program in the SRAM, the parameters, the home position
data etc. will be lost.
