Danfoss VLT AutomationDrive FC 361 Programming Guide

NOTICE
Changing parameter 4-16 Torque Limit Motor Mode when
parameter 1-00 Conguration Mode is set to [0] Speed
open loop, parameter 1-66 Min. Current at Low Speed is
automatically readjusted.
NOTICE
The torque limit reacts to the actual, non-ltered torque,
including torque spikes. This is not the torque that is
seen from the LCP or the eldbus as that torque is
ltered.
4-17 Torque Limit Generator Mode
Range: Function:
100 %* [ 0 -
1000.0 %]
This function limits the torque on
the shaft to protect the mechanical
installation.
4-18 Current Limit
Range: Function:
Size
related*
[ 1.0 -
1000.0 %]
NOTICE
If [20] ATEX ETR is selected in
parameter 1-90 Motor Thermal
Protection, set
parameter 4-18 Current Limit
current limit to 150%.
This is a true current limit function
that continues in the oversyn-
chronous range. However, due to
eld weakening the motor torque
at current limit will drop
accordingly when the voltage
increase stops above the
synchronized speed of the motor.
4-19 Max Output Frequency
Range: Function:
Size
related*
[ 1 - 590 Hz]
NOTICE
This parameter cannot be
adjusted while the motor is
running.
NOTICE
Maximum output frequency
cannot exceed 10% of the
inverter switching frequency
(parameter 14-01 Switching
Frequency).
Provides a nal limit on the output
frequency for improved safety in
applications where overspeeding is
to be avoided. This limit is nal in
4-19 Max Output Frequency
Range: Function:
all congurations (independent of
the setting in
parameter 1-00 Conguration Mode).
4.5.2 4-2* Limit Factors
4-20 Torque Limit Factor Source
Option: Function:
Select an analog input for scaling
the settings in
parameter 4-16 Torque Limit Motor
Mode and parameter 4-17 Torque
Limit Generator Mode 0–100% (or
inverse). The signal levels
corresponding to 0% and 100% are
dened in the analog input scaling,
for example parameter group 6-1*
Analog Input 1. This parameter is
only active when
parameter 1-00 Conguration Mode
is in Speed Open Loop or Speed
Closed Loop.

other way around). The signal levels
corresponding to 0% and 100% are
dened in the analog input scaling,
for example parameter group 6-1*
Analog Input 1. This parameter is
only active when
parameter 1-00 Conguration Mode
is in [4] Torque Open Loop.
