Description
Fieldbus interface as the source for ramp pair 1/2 selection,
ie, Control word 0301 FB CMD WORD 1
word is sent by the fieldbus controller through the fieldbus
adapter or embedded fieldbus (Modbus) to the drive. For
the Control word bits, see section
profile on page 333.
Note: This setting applies only for the DCU profile.
Sequence programming ramp defined by parameter
ST1 RAMP (or 8423/.../8492)
Inverted digital input DI1. 0 = ramp pair 2, 1 = ramp pair 1.
See selection DI1(INV).
See selection DI1(INV).
See selection DI1(INV).
See selection DI1(INV).
Defines the acceleration time 1, ie, the time required for the
speed to change from zero to the speed defined by
parameter 2008 MAXIMUM FREQ
MAXIMUM SPEED (in vector control). The control mode is
selected by parameter
• If the speed reference increases faster than the set
acceleration rate, the motor speed will follow the
acceleration rate.
• If the speed reference increases slower than the set
acceleration rate, the motor speed will follow the
reference signal.
• If the acceleration time is set too short, the drive will
automatically prolong the acceleration in order not to
exceed the drive operating limits.
Actual acceleration time depends on parameter
SHAPE 1 setting.
