* 1. There is no P1 terminal for a Servopack with a
capacity of less than 5 kW.
* 2. Fordetails on MECHATROLINKconnections,
see 4.2.4.
* 3. When a brake built into the motor or an exter-
nal brake is used, a BRK signal is received by
the relay and controls the brake.

* 5. For Zero point return methods 1 and 2, con-
nect ZERO signal (Zero point LS) to /EXT sig-
nal.
