14.1.77 L_JogCtrlExtension_1
This FB can be connected upstream to the L_NSet
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
"Switch-off positioning" TA.
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
bRfgIn
BOOL
Ramping down of the setpoint generator in the downstream L_NSet FB according to
the Truth table
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.
• If, in addition to the bJog1In and bJog2In inputs, other jog signals are set at the
L_NSet
FB, new fixed setpoints are reached, and the drive traverses at speeds that
differ from the selection via bJog1In and bJog2In.
bSlowDown1
bSlowDown2
bSlowDown3
BOOL
Activation of fixed setpoint 2 in the downstream L_NSet FB
• These inputs only fulfil a function if they have been activated via bInputSel1 and
bInputSel2 previously (see Truth table
).
bStop1
bStop2
bStop3
BOOL
Ramping down of the ramp function generator in the downstream L_NSet FB
• These inputs only fulfil a function if they have been activated via bInputSel1 and
bInputSel2 previously (see Truth table
).
