12.11 L_JogCtrlExtension_1
This function extension is available from version 05.00.00!
This FB is connected upstream to the L_NSet_1 ramp function generator/setpoint generator to
implement a switch-off positioning at limit switch.
• Detailed information on this operating mode can be found in the description of the TA "Switch-
off positioning" . ( 238)
Inputs
Identifier
Data type
Information/possible settings
bInputSel1
bInputSel2
BOOL
Activation of the bSlowDown1/bStop1, bSlowDown2/bStop2 and bSlowDown3/
bStop3 signal pairs according to the Truth table for activating the pre-switch off
bRfgIn
BOOL
Ramping down the ramp function generator in the downstream FB L_NSet_1
according to the Truth table - switch-off positioning
bJog1In
bJog2In
BOOL
Selection inputs for setting fixed speeds in the setpoint generator
• If the pre-switch off is inactive (bInputSel1 and bInputSel2 are both set to FALSE),
the two control signals are output one-to-one at the bJog1Out and bJog2Out
outputs.
• To achieve the desired behaviour (starting at high speed, pre-switch off at low
speed), both inputs must be set to TRUE.
• Fixed setpoint 2 must be less than fixed setpoint 3!
Otherwise, the drive will start at a low speed and accelerate after the pre-switch
off.
bSlowDown1
bSlowDown2
bSlowDown3
BOOL
Activation of the fixed setpoint 2 in the downstream FB L_NSet_1
• These inputs only fulfil a function if they have been activated via bInputSel1 and
bInputSel2 previously (see Truth table for activating the pre-switch off ).
bStop1
bStop2
bStop3
BOOL
Ramping down of the ramp function generator in the downstream FB L_NSet_1
• These inputs only fulfil a function if they have been activated via bInputSel1 and
bInputSel2 previously (see Truth table for activating the pre-switch off ).
