Outputs
Parameter
bLoadExtSpeedSetpoint
BOOL
Loading of the ramp generator with the motor-based speed setpoint
dnExtSpeedSetpoint_n.
TRUE The input signal dnExtSpeedSetpoint_n is loaded into the ramp gene-
rator.
dnExtSpeedSetpoint_n
DINT
Motor-based speed setpoint in [%]
• Is loaded into the ramp generator by setting bLoadExtSpeedSetpoint to TRUE.
bLoadActualMotorSpeed
BOOL
Loading of the ramp generator with the motor-based actual speed
dnActualMotorSpeed_n.
TRUE The input signal dnActualMotorSpeed_n is loaded into the ramp ge-
nerator.
dnActualMotorSpeed_n
DINT
Motor-based actual speed value in [%]
• Is loaded into the ramp generator by setting bLoadActualMotorSpeed to TRUE.
dwRampMode
DWORD
Type of profile generation
• Can also be set via C04220.
0 Profile generation with linear ramps.
• Relating to the reference speed (C00011)
1 Profile generation with jerk limitation (S ramps).
10 Profile generation with linear ramps.
• Relating to the reference speed (C00011)
• In case of edge change at the bStop input with regard to the cur-
rent setpoint (constant time).
• The setpoint applied to the input dnExtSpeedSetpoint_n is adop-
ted as starting value.
AxisData Machine parameters
• For calculation and display of reference values on the load side (output shaft
speed, machine speed) the reference speed (C00011), the gearbox factor and the
feed constant are required.
• For accepting the machine parameters of the drive/motor, connect this input
with the output DI_AxisData of the SB LS_DriveInterface.
Identifier/data type Value/meaning
dnSpeedSetpointOut_n
DINT
Output setpoint
• Relating to the reference speed (C00011)
bStoppingActive
BOOL
Status signal "Ramp-down is active"
• Ramp-down can be activated via the input bStop.
TRUE The ramp generator leads the current output value to "0" (standstill).
TRUEFALSE The output value equals "0" (standstill).
dnTargetSetpoint_n
DINT
Current target setpoint (at the input of the ramp generator)
• Relating to the reference speed (C00011)
bSetpointOutInTarget
BOOL
Status signal "Default value reached"
TRUE The output of the ramp generator has reached the default value (in
consideration of the window set).
