Information/possible settings
bSetTPReceived
BOOL
Input for status signal "Touch probe detected"
FALSE
TRUE Touch probe or zero pulse received.
dnSetTPPos_p
DINT
Input for accepting the position measured via touch probe
nIn_v
INT
Speed setpoint of the master
• Scaling: 16384
≡
15000 rpm
bRfg0
BOOL
Ramp down ramp function generator to "0" (quick stop function)
• This input can, for instance, be connected to the status signal "quick stop active".
TRUE Ramp down the ramp function generator to "0"
• The drive is brought to a standstill with the deceleration time set
.
bRfgStop
BOOL
Stop ramp function generator
TRUE Stop ramp function generator
• The last status is output to
nOut_v
.
• The speed/angle setpoint
nIn_v
is saved.
• After
bStop

the ramp function generator.
bReset
BOOL
Reset added angle setpoint
TRUE The internally added angle setpoint is reset and the ramp function
generator is activated. If the status signal
