Figure 8-25 Start optimizer
In Open-Loop mode this parameter is not used.
Nominal Elevator Speed
(
E01
) defines the maximum linear speed in mm / s which is equivalent to an analog reference of 100 %.
If
Control Input mode
(
H11
) = Analog Run Prmit (0) then a reference from -10 V to 10 V is expected. If
Control Input mode
(
H11
) = Analog 2 Dir (1)
then a reference from 0 V to 10 V is expected.
10 V = 100.00 % = 32767 =
Nominal Elevator Speed
(
E01
).
If the elevator controller outputs less than 10 V at full speed e.g. 9.8 V, then it is possible to compensate for this using the analog input's scaling factor.
On start up, the profile generator is used to ramp the speed from 0 to the analog reference level and is then bypassed once the speed is reached.
This smoothes out the transition from 0 to the analog reference where the analog reference starts > 0 V e.g. in open loop the user may apply a small
speed to improve holding torque prior to brake release.
When set to Off (0), the analog speed reference filter is bypassed.
When set > 0, the analog speed reference filter is active and the time constant of the filter is
Analog Speed Reference Filter Time Constant
(
G50
) ms.
Due the internal sample rate the time constant for the filter responds in units of 4 e.g. 4, 8, 12, 16 etc, where a value that is not divisible by 4 will be
rounded down to the nearest value divisible by 4 e.g. 9 will be rounded down to 8 ms time constant.
The filter will be implemented such that the filter accumulator will be held constant if the time constant changes allowing the filter to be modified on the
fly.
The start optimizer is always used in Open-Loop mode to provide a holding speed reference for brake release. A request to release the
brake in Open-Loop will not be made unless Start Optimizer Speed (
G46
) is reached.
