L_JogCtrlExtension_1
This FB can be connected upstream to the
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
Inputs

Data type
Information/possible settings
bInputSel1
bInputSel2
BOOL
Activation of the
bSlowDown1/bStop1
,
bSlowDown2/bStop2
and
bSlowDown3/bStop3
signal pairs according to the
bRfgIn
BOOL
Ramping down of the setpoint generator in the downstream
FB according to
the
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
FB, new fixed setpoints are reached, and the drive traverses at speeds that
differ from the selection via
bJog1In
and
bJog2In.

Activation of fixed setpoint 2 in the downstream
• These inputs only fulfil a function if they have been activated via
bInputSel1
and

BOOL
Ramping down of the ramp function generator in the downstream
