Carrying out the
fi
rst test run
Warning!
Operating synchronous motors without encoder offset can cause uncontrolled motor movements
An encoder offset adjustment must be made in synchronous motors before starting the
fi
rst time (see
chapter "Special Functions")!
The offset calibration has already been performed in the factory for ZIEHL-ABEGG motors.
If third-party motors are used, the offset must be performed as follows (obtain information from
manufacturer): Connect motor winding to DC voltage: U
R
+ and V and W
R
-. Offset value = 0
The
fi
rst trip must be carried out with the return control or as an inspection trip.
If this trip can be carried out without any problems and without any fault messages, a normal trip can
be made as the next step.
If fault messages appear, an error list is available in the
“
Diagnose
”
chapter together with the
corresponding error causes

Optimisation of the startup and drive behaviour
The "SPD_KP" (ampli
fi
cation) parameter can be used to optimise the setting of the speed controller
acting during travel. The parameter can be changed in the
Control/SPD_KP
menu.

Speed controller basic
gain
You can generally set the speed control by changing the factor for the basic ampli
fi
cation ("SPD_KP").
If signi
fi
cant control deviations occur during the trip (especially during acceleration and deceleration),
(see Fig.), the ampli
fi
cation has been set too low. In this case, increase the factor for ampli
fi
cation
("SPD_KP").
