Safe torque off
For the drive to start, both STO connections (OUT1-IN1 and OUT1-IN2) 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.
Auxiliary voltage connection
The drive has 24 V DC (±10%) auxiliary power supply terminals both on the base
unit and on the RIIO-01 module. You can use them:
• to supply auxiliary power from the drive to external control circuits or option
modules
• to supply external auxiliary power to the drive to keep the control and cooling
in operation if there is a power outage.
See the technical data for the specifications for the auxiliary power supply terminals
(input/output).
To supply power to external control circuits or option modules:
1. Connect the load either to the auxiliary power output on the base unit, or on
the RIIO-01 module (+24V and DGND terminals).
2. Make sure that you do not exceed the load capacity of the output, or the sum
load capacity of both outputs.
