3-95 Ramp Delay
Range:
Function:
Size

*
[ 0 - 0]
Enter the delay required from
activation of the digital potenti-
ometer function until the frequency
converter starts to ramp the
reference. With a delay of 0 ms, the
reference starts to ramp when
increase/decrease is activated. See

4.5 Parameters: 4-** Limits/Warnings
4.5.1 4-1* Motor Limits
Define torque, current, and speed limits for the motor, and
the reaction of the frequency converter when the limits are
exceeded.
A limit may generate a message in the display. A warning
always generates a message in the display or on the
fieldbus. A monitoring function may initiate a warning or a
trip, after which the frequency converter stops and
generates an alarm message.
4-10 Motor Speed Direction
Option:
Function:
NOTICE
This parameter cannot be
adjusted while the motor is
running.
Select the motor speed direction(s)
required. Use this parameter to
prevent unwanted reversing. When
parameter 1-00 Configuration Mode
is set to
[3] Process
,
parameter 4-10 Motor Speed
Direction
is set to
[0] Clockwise
as
default. The setting in
parameter 4-10 Motor Speed
Direction
does not limit options for
setting
.
[0]
Clockwise
The reference is set to CW rotation.
Reversing input (default terminal
19) must be open.
[1]
Counter
clockwise
The reference is set to CCW
rotation. Reversing input (default
terminal 19) must be closed. If
reversing is required with
reverse
input open, the motor direction can
be changed by
parameter 1-06 Clockwise Direction
.
[2]
Both
directions
Allows the motor to rotate in both
directions.
