9.7.2 Extended control settings
In the case of a deceleration to stop, i.e. during
stopping or a direct
landing operation, a position controller is active. This controller
continuously compares the actual position to the set position and
compensates any deviations. This is a prerequisite for an exact landing
operation. By increasing the parameter LR, the position controller can be
reinforced and position deviations can be balanced faster. If you enter 0,
the position controller is switched off completely.
Note : An excessive gain can result in vibrations when the elevator stops.
Limitation of maximum motor current.
Proportional current regulator gain.
Note: Change parameters only after consultation with RST Elektronik.
P-gain current regulator.
Note: Change parameters only after consultation with RST Elektronik.
I-gain current regulator.
Note: Change parameters only after consultation with RST Elektronik.
The variable of the speed controller can be smoothened in order to obtain
a smoother behaviour.
Note: High values can result in vibration.
In case low-pulse encoders are used, the scanning time of the speed
controller can be increased in order to obtain a better speed resolution. If
the scanning time is too long, this can result in control vibrations.
After changing the scanning time, the unit must be switched off and on
again in order for the new setting to become effective.
Note: Change parameters only after consultation with RST Elektronik.
PWM frequency of converter
Here you can adjust another controller type for load take-over
Note: Change parameters only after consultation with RST Elektronik.
Preset load for load equilibrium: A basic torque is preset when the brake
is opened (static load compensation). This parameter is to be set in
percent.
LV = 500 means symmetrical weight equilibration, no preset torque.
Values < 500 mean a preset torque in down direction.
Values < 500 mean a preset torque in up direction.
A difference of 100 equals a preset torque of 10 %.
Example :
LV = 400 -> a preset torque of 10% in down direction
LV = 700 -> a preset torque of 20% in up direction
