8.7 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").
Control deviations when the ampli
fi
cation is set too low
blue Set-value - travel speed
red Actual-value - travel speed
If the motor is noisy or starts vibrating (see
fi
gure), ampli
fi
cation is set too high. In this instance, the
factor for ampli
fi
cation ("SPD_KP") should be reduced.

cation is set too high

Optimum setting of the speed controller
The following procedure is recommended to obtain an optimum setting of the speed controller:
Increase the parameter
Loop control/SPD_KP
until the motor causes noises/vibrations when starting
up.
Decrease the parameter
Loop control/SPD_KP
until the motor causes no noises/vibrations when
starting up.
Turning away when starting up
Turningawaywhen starting up is indicated by uncontrolled movement of the traction sheave. The
reason for this is too weak a gain of the speed controller for the time at which the brake opens.
If the motor turns away when starting up despite optimum setting of the basic gain (parameter
Control/SPD_KP
), this can be optimised by increasing the parameter
Startup/K_START
.
