Safe torque off
For the drive to start, both STO connections (S+ to S1 and S+ to S2) must be closed.
By default, the terminal block has jumpers to close the circuit. Remove the jumpers
before connecting external Safe torque off circuitry to the drive. See chapter
The
Safe torque off function .
Communication mode jumper J2
The drive with below hardware revision doesn't have J2, and does not need to
switch between panel and Modbus mode.
