Readjustment
Correction of the rope elongation under load and relieving the load on the car. The rope elongation is
evaluated by the control system.
The readjustment speed is con
fi
gured in the
Travelling/V_Z"
menu and controlled through a digital
input (con
fi
gured to V_Z).
Information
The traveling speed for readjustment takes precedence over the other traveling speeds.
To be able to make a readjustment, at least the following input signals need to be present:
•
Controller enable
•
Readjustment speed V_Z
•
Direction default
Information
To prevent oscillation, the control system must wait a suitable amount of time until the rope comes to
rest before the readjustment is activated.

Operation in idle
With the ZETADYN 4C frequency inverter, both synchronous as well as asynchronous motors can be
operated in an idle state.
CAUTION!
Caution!
When operating synchronous motors in idle, strong vibrations and noise development can
result! Therefore, the factor for the speed controller basic-ampli
fi
cation "SPD_KP" must be
reduced to approx. 0.1%.
