Tip!
The distribution for product xxx will cease soon.
Recommendation: Select an alternative product or contact your Lenze distribution partner.
Cause Effects Possible remedies
The product has been discontinued
and shall not be used anymore for
drive dimensioning.
Maybe the product is not available
anymore.
• Select current product.
• Contact Lenze sales partner.
Note!
No effective starting current limitation available.
For DC-bus capacity of the DC-bus connection, an external charging connection may be required.
Cause Effects Possible remedies
Without an effective starting current
limitation, the devices must not be
connected in parallel.
Devices will be destroyed. Take appropriate measures after
consultation with your Lenze sales
partner.
Note!
During the dimensioning phase, no measures for the dissipation of generated power have been taken.
The hoist drive generates regenerative power during the lowering phase that has to be dissipated.
Cause Effects Possible remedies
A hoist drive generates regenerative
power during the lowering operation
that has to be dissipated by the in-
verter.
The lowering operation has not been
configured in the DSD.
Hoist sags. • Use electrical braking compo-
nents.
• Use regenerative power supply
modules.
Note!
Check whether the drive system and the tensile force sensor are suitable for the torque setting range xxx
and the tensile force setting range yyy.
Recommendation: Use low-friction mechanical transmission elements between the motor and the wind-
ing shaft as well as a KTY sensor for the compensation of the motor temperature.
Cause Effects Possible remedies
The torque setting range results from
the entered values for tensile force
and diameter.
Minimum tensile forces cannot be
reached or cannot be repeated.
• Carry out recommended meas-
ures.
