Lenze i550 Series Project Planning Manual

Residual hazards
Even if notes given are taken into consideraon and protecve measures are implemented,
the occurrence of residual risks cannot be fully prevented.
The user must take the residual hazards menoned into consideraon in the risk assessment
for his/her machine/system.
If the above is disregarded, this can lead to severe injuries to persons and damage to prop-
erty!
Protecon of persons
Before working on the inverter, check if no voltage is applied to the power terminals.
•
Depending on the device, the power terminals X105 remain live for up to 3 ... 20 minutes.
•
The power terminalsX100 and X105 remain live even when the motor is stopped.
Motor protecon
With some sengs of the inverter, the connected motor can be overheated.
•
E. g. by longer operaon of self-venlated motors at low speed.
•
E. g. by longer operaon of the DC-injecon brake.
Protecon of the machine/system
Drives can reach dangerous overspeeds.
•
E. g. by seng high output frequencies in connecon with motors and machines not suita-
ble for this purpose.
•
The inverters do not provide protecon against such operang condions. For this pur-
pose, use addional components.
Switch contactors in the motor cable only if the controller is inhibited.
•
Switching while the inverter is enabled is only permissible if no monitoring funcons are
acvated.
Motor
If there is a short circuit of two power transistors, a residual movement of up to 180°/number
of pole pairs can occur at the motor! (e. g. 4-pole motor: residual movement max. 180°/2 =
90°).
Parameter set transfer
During the parameter set transfer, control terminals of the inverters can adopt undened
states.
•
Thus, the control terminal of the digital input signals have to be removed before the trans-
fer.
•
This ensures that the inverter is inhibited. The control terminals are in a dened state.
Degree of protecon - protecon of persons and device protecon
•
Informaon applies to the mounted and ready-for-use state.
•
Informaon does not apply to the wire range of the terminals.
-
Terminals that are not assigned only have a low protecon against contact.
-
Terminals for large cable cross-secons have lower classes of protecon, e. g. from
15 kW IP10 only.
Commissioning
If you use the Applicaon Loader as a download tool for safety-related parameter sets, vali-
date the parameter sets aer the download.
Device exchange without tool
Exchange a maximum of one safe device before recommissioning.
Exchange of devices
Test the compability of the devices before exchanging.
