Controlling Inverter Torque
Section 4-4
Step 1
Configure the Option Board and Network as explained in sections
3-1 Installa-
tion of EDS files
and
3-2 Configuring the Option Board
with Control IO and
Multi function IO monitor (Output assembly 101, Input assembly 151). There
are two options:
• When using Fixed allocation method of configuring the master, select
P046 = 4.
• When using User-set allocation, select the two Extended Control IO and
Multi-function IO monitor assemblies.
Step 2
Set C003 = 52 (ATR: permission of torque command input) to assign intelli-
gent input terminal 3 as torque enable. See also section
4-3 Overriding
Inverter inputs
Step 3
Set parameter A044=3 to enable Sensorless Vector Control (SLV).
Step 4
Set parameter P033=6 to assign Torque command input selection to Option
Board.
Step 5
Restart the Inverter or reset the Option Board for the new settings to take
effect.
Note
The Inverter will only allow setting of torque related registers if it is configured
to operate with CT rating in Std. IM mode.
Your input and output process areas should now have the following layout:
Step 6
Set the maximum allowable output frequency in torque mode by configuring
P039 and P040 for the forward- and reverse run directions. Be careful to
select safe limits for your test setup.
