Function blocks
3.2.100 Virtual master (VMAS)
3−319
l
EDSVS9332K−EXT EN 4.0
3.2.100.4 Inching mode
l Activate: VMAS1−EN−AIN = LOW
l Activate inching speed from C1461/1:
VMAS1−CW = HIGH and VMAS1−CCW = LOW
l Parameter setting for inching speed: C1461/1
l Activate inching speed from C1461/2:
l VMAS1−CCW = HIGH and VMAS1−CW = LOW
l Set inching speed n = 0: VMAS1−CCW = LOW and VMAS1−CW = LOW
l With VMAS1−CCW = HIGH and VMAS1−CW = HIGH the status remains the same.
Tip!
For inching, activate the ramp function generator by setting VMAS1−EN−RFG = HIGH.
Code Meaning Note
C1461/1 Speed for VMAS1−CW = HIGH in rpm
C1461/2 Speed for VMAS1−CCW = HIGH in rpm
3.2.100.5 Ramp function integrator
With the ramp function integrator the setpoint can be smoothly set to the target point.
l Activate: VMAS1−EN−RFG = HIGH
Code Meaning Note
C1462/1 Acceleration time in seconds
C1462/2 Deceleration time in seconds
The ramps set under C1462/1 and −/2 are assigned to the output VMAS1−DFOUT.
STOP!
If the ramp function generator is used together with the input VMAS−DFIN, pulse losses occur (no
phase synchronism) and this drive loses the contact with the master.
The HIGH signal at the output VMAS1−RFG−IN=OUT indicates that the ramp function generator has
reached its setpoint. For this status message a window (C1463/1) and a hysteresis (C1463/2) can be
set.
