Value/meaning
bRfgOut
BOOL
Control signal for ramping down the setpoint generator
• Connect this output to the bRfg0 input of the L_NSet FB.
bJog1Out
BOOL
Control signal for setting fixed speeds in the setpoint generator
• Connect this output to the bJog1 input of the L_NSet FB.
bJog2Out
BOOL
Control signal for setting fixed speeds in the setpoint generator
• Connect this output to the bJog2 input of the L_NSet FB.
Input Function Response in the L_NSet FB
bInputSel1 bInputSel2
FALSE FALSE Pre-switch off inactive No response
• The bRfgIn input signal is directly
provided at the bRfgOut output.
• The bJogIn1 and bJogIn2 input signals are
directly output at the bJog1Out and
bJog2Out outputs.
TRUE FALSE The bSlowDown1 and bStop1 inputs
are evaluated.
Pre-switch off can be activated
• If the SlowDown function is activated via
the selected bSlowDown input, fixed
setpoint 2 in the setpoint generator is
activated via the bJog1Out and bJog2Out
outputs.
• If the Stop function is activated via the
selected bStop input, the bRfgOut output
is set to TRUE and hence the setpoint
generator is deactivated.
FALSE TRUE The bSlowDown2 and bStop2 inputs
are evaluated.
TRUE TRUE The bSlowDown3 and bStop3 inputs
are evaluated.
