Parameters: 4-** Limits/Warnings - Danfoss VLT AutomationDrive FC 361 Programming Manual

Parameter Descriptions
3-95 Ramp Delay
Range: Function:
Size [ 0 - 0] Enter the delay required from
related 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
also parameter 3-91 Ramp Time.

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 parameter 4-13 Motor Speed
High Limit [RPM].
[0] Clockwise The reference is set to CW rotation.
Reversing input (default terminal
19) must be open.
[1] Counter The reference is set to CCW
clockwise 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 Allows the motor to rotate in both
directions directions.

Function:
[ 0 - par. 4-13 Enter the minimum limit for motor
RPM] speed. The motor speed low limit
can be set to correspond to the
manufacturer's recommended
minimum motor speed. The motor
speed low limit must not exceed
the setting in parameter 4-13 Motor
Speed High Limit [RPM].
Function:
[ 0 - par. 4-14 Enter the minimum limit for motor
Hz] speed. The motor speed low limit
can be set to correspond to the
minimum output frequency of the
motor shaft. The motor speed low
limit must not exceed the setting in
parameter 4-14 Motor Speed High
Limit [Hz].
Function:
[ par. 4-11 - Enter the maximum limit for motor
60000 RPM] speed. The motor speed high limit
can be set to correspond to the
manufacturer's maximum nominal
motor speed. The motor speed high
limit must exceed the setting in
parameter 4-11 Motor Speed Low
Limit [RPM].
Function:
[ par. 4-12 - Enter the maximum limit for motor
par. 4-19 Hz] speed in Hz. Parameter 4-14 Motor
Speed High Limit [Hz] can be set to
correspond to the manufacturer's
recommended maximum motor
speed. The motor speed high limit
must exceed the value in
parameter 4-12 Motor Speed Low
Limit [Hz]. The output frequency
must not exceed 10% of the
switching frequency
(parameter 14-01 Switching
Frequency).
Function:
[ 0 - This function limits the torque on
1000.0 %] the shaft to protect the mechanical
