the risk of an effect into the danger zone is reduced. (ATEX Directive 94/9/EG,
Appendix II, section 1.6.2)
The user has the following possibilities:
● Energy isolation is guaranteed from the exit of the drive device, if at emer‐
gency stop, in addition to the power loss, the drive device is locked
electronically. This is done by switching off the power contactor - with
subsequent failure reaction of the drive device because of power failure
(cp. F281). Adjusting the required drive-end failure reaction must be made
by the user at the drive device via the drive parameters (cp. P-0-0119)
according to the functional description.
● To have the encoder feeder cable also de-energized, shut down the con‐
trol voltage of the drive device.
After the control voltage and the power of the drive device are interrupted, the
exit on the motor side has electronically locked itself over the output stage and
eventually stored energies in the intermediate direct current link are therewith
isolated on the motor side and on the output side.
● The intermediate direct current link short-circuit can be used – if possible
– to reduce the energies within the intermediate direct current link of the
drive device after shutdown of supply voltage fast.
Irrespective of these possibilities, the user has to check – as stipulated in the
notes regarding safety - by means of an appropriate measuring instrument, in
general, before working on the machine, if the machine or parts of it are under
residual voltage (e.g. caused by rest energy of condensers in filters and drive
devices etc.). Wait for their discharging time.
Heed the following regarding dangers caused by other disturbances:
● Operation only inside the specified ambient conditions,
● Do not exceed the maximum vibration and shock loads.
● Prevent corrosion due to humidity, aggressive substances and soiling of
the protective conductor connections.
