WARNING
Unexpected movement due to overload
In case of overload of the drive there is a risk that the motor will "break down" (sudden loss of torque).
An overload may be caused e.g. by inadequate dimensioning of the drive unit or by the occurrence of
sudden peak loads. Sudden peak loads may be of a mechanical origin (e.g. blockage) or may be
caused by extremely steep acceleration ramps (P102, P103, P426).
Depending on the type of application, "breakdown" of the motor may cause unexpected movement
(e.g. dropping of loads by lifting equipment).
To prevent any risk, the following must be observed:
• For lifting equipment applications or applications with frequent large load changes, parameter
P219 must remain in the factory setting (100 %).
• Do not inadequately dimension the drive unit, provide adequate overload reserves.
• If necessary, provide fall protection (e.g. for lifting equipment) or equivalent protective measures.
A description of the relevant parameters for the frequency inverter can be found below. Access to the
parameters is via a parameterisation tool (e.g. NORDCON software) or a control or parameterisation
box (Chap. 1.3 "Scope of delivery")and enables optimal adjustment of the frequency inverter to the
drive application. Dependencies of the relevant parameters may result from the various configurations
of the frequency inverters.
Information
Restricted visibility of parameters with external 24 V supply
Via terminal 44 the device can be externally supplied with 24 V (X6). This enables the values of most
parameters to be read out and changed by the usual parameterisation methods. However, this does
not apply for all parameters. The available display range is limited and essentially consists of the
setting values for bus communication (Ethernet, CANopen, USS). The device status is not available if
the mains supply is not connected (X1). Except for the communication sector, the device is therefore
in a switched-off state. For complete diagnosis of the device, a mains supply (X1) is required (230 V
for single phase devices, 400 V for 3-phase devices).
Information
Ethernet parameterisation
With power supply via USB (X169 the parameter for setting the Ethernet dialect cannot be changed,
Unless 24 V is connected to terminal X6.
Every frequency inverter is factory-set for a motor of the same power. All parameters can be adjusted
"online". Four switchable parameter sets are available during operation. The scope of the parameters
to be displayed can be influenced using the supervisor parameter
P003 .
The relevant parameters for the device are described in the following. Explanations for parameters
which concern the field bus options or the special functionality of the POSICON, for example, can be
obtained from the respective supplementary manuals.
The individual parameters are combined into functional groups. The first digit of the parameter number
indicates the assignment to a
menu group :
