Safety instructions

Danger!
If the request for the safety function is cancelled, the drive will restart
automatically.
You must provide external measures which ensure that the drive only restarts
after a confirmation (EN 60204).

Danger!
Unexpected motor rotation possible
In the event of a short-circuit between two power transistors, a residual
movement of the motor of up to 180 °/number of pole pairs may occur!
(Example.: 4-pole motor ⇒ residual movement max. 180 °/2 = 90 °)
Possible consequences:
ƒ People may be injured by the machine movements (unexpected start-up).
Protective measures:
ƒ The residual movement must be considered in the risk analysis, e.g. safe
torque off for main spindle drives.

Warnings!
ƒ Maximum surrounding air temperature: 55 °C.
ƒ External fuse for 24 Vdc supply voltage. Rated 4 A DC fuse UL248-14.
