Actual signals and parameters 233
COMM
Fieldbus interface as the source for ramp pair 1/2 selection,
ie, Control word
bit 10. The Control
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
on page
.
Note:
This setting applies only for the DCU profile.

2202 ACCELER
TIME 1
Defines the acceleration time 1, ie, the time required for the
speed to change from zero to the speed defined by
parameter
(in scalar control) /
(in vector control). The control mode is
.
• 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
setting.
