4.7.5
Limit value monitoring with hysteresis
The block supports the standard function limit value monitoring with hysteresis. The function
is executed via the
AV_Hyst
input parameter.
4.7.6
Rapid stop
Rapid stop has the highest priority in manual and automatic mode, and in all other operating
states (e.g. forcing of states). The function is activated via the faceplate. This depends on
the parameterization in the Enable rapid stop via faceplate feature bit.
You enter the command for rapid stop via the
RapidStp = 1
input parameter.
The drive is stopped immediately by clicking the "Rapid stop" button in the faceplate. This is
displayed in the faceplate:
For implementation of the rapid stop function for local operation, the
R_StpAct = 1
output
parameter is set. You must interconnect this parameter with the relevant channel block and
in the I/Os to implement this rapid stop function in the hardware.
Release of the rapid stop for all modes is performed in the faceplate via the "Reset" button
(
RstOp = 1
). In the CFC, release is performed via the
RstLi = 1
input parameter. In
automatic mode, release can also be performed via a 0-1 edge transition of the control if the
Feature.Bit9 = 1
.
Rapid stop can also be selected in the stop state of the motor. This also prevents the motor
from starting.
4.7.7
Specify warning times for controls
The MMRevDhl block supports the Specify warning times for controls function.
You can generate warning signals when motors are started. Warning signals can be
generated in the following modes:
●
Manual mode (
WarnTiMan
input parameter)
●
Automatic mode (
WarnTiAut
input parameter)
You specify the warning times in seconds using the
WarnTiMan
and
WarnTiAut
input
parameters. If a motor is started, this is displayed in the output parameter with
WarnAct = 1
.
The motor then starts after the set warning times has elapsed and
WarnAct
is reset
(
WarnAct = 0
).
A warning to this effect will not be output if you set a value smaller than the
SampleTime
parameter for the warning times (
WarnTiMan, WarnTiAut
).
