Technical description 8100_ A
Controller enable after chan ging the operating mode C001
The operating mode can only be changed if the controller is inhibited first. The
controller can only be enabled by the input channel, which has been used to inhibit
the controller.
Controller enable when chan ging the parameter sets C002
Before changing the parameter sets, the controller must be inhibited. Loading another
parameter set causes the controller to be initialized again. It then acts as after mains
connection.
Caution! When changing the parameter sets or loading factory setting, the drive
may accelerate if it has not been inhibited via terminal 28 first.
7.3.2 INVERTSET-VALUEC041
QUICKSTOPC042
Codes C041 and C042 are provided for the functions:
Invert set-value and
Activate quick stop
Depending on the operating mode C001, the codes have a direct effect on the
functions or display the state of the control terminals 21 and 22. Also, in case of
terminal control, the function of the terminals 21 and 22 can be changed using C176
(see 7.6.191.
Quick stop function
By activating quick stop, the drive is decelerated along the pre-set deceleration ramp
with C105. When reaching fd
= 0 Hz, the output voltage corresponds to the value
Uminset with C016
(see 7.2.51.
In addition. a DC brake can be activated via C019 using a holding time to be set with
C107. After the holding time, the inverter changes its output voltage to OV.
Keypad
or LECOM operation:
For keypad or LECOM operation (C001 = -1-, -3-1. the set-value is inverted with
C041 and quick stop is activated with C042. The terminals 21 and 22 are always
active in these operating modes.
