1) The cable selection is based on max. 9 cables laid on a cable ladder side by side, three ladder type trays one on top
of the other, ambient temperature 30 °C (86 °F) PVC insulation, surface temperature 70 °C (158 °F) (EN 60204-1 and
IEC 60364-5-52). For other conditions, select the cables according to local safety regulations, appropriate input
voltage and the load current of the drive.
2) The cable selection is based on NEC Table 310-16 for copper wires, 75 °C (167 °F) wire insulation at 40 °C (104 °F)
ambient temperature. Not more than three current-carrying conductors in raceway or cable or earth (directly buried).
For other conditions, dimension the cables according to local safety regulations, appropriate input voltage and
the load current of the drive.
Temperature: For IEC, select a cable rated for at least 70 °C maximum permissible
temperature of conductor in continuous use. For North America, power cables must
be rated for 75 °C (167 °F) or higher.
Voltage: 600 V AC cable is accepted for up to 500 V AC.

Safe torque off (STO) Saaran testi
The drive has a Safe torque off (STO) function in accordance with IEC/EN 61800-5-2.
It can be used, for example, as the final actuator device of safety circuits that stop
the drive in case of danger (such as an emergency stop circuit).
When activated, the STO function disables the control voltage of the power
semiconductors of the drive output stage, thus preventing the drive from generating
the torque required to rotate the motor. The control program generates an indication
as defined by parameter 31.22. If the motor is running when STO is activated, it coasts
to a stop. Closing the activation switch deactivates STO. Any faults generated must
be reset before restarting.
