8 PARAMETERIZING THE SPEED AND TORQUE LIMITS
Information that you will find in
this chapter …
This chapter gives you information on:
• the torque and speed limits which the Comfort Reference Value application offers
• how to change these limits during operation
• and how to set the limits.
8.1 Torque Limits
Information that you will find in
this section …
This section gives you information on:
• what absolute or motoring / generating torque limits are
• which torque limits apply in speed and torque operation
• and how the torque can be limited by additional functions.
You can choose between absolute and motoring / generating limits for variable torque
limitation. Remember that motoring / generating limitation is only available with speed
control.
Absolute torque limits
Absolute torque limits are not dependent on the direction of speed and torque.
Two absolute torque limits can be used in the Comfort Reference Value application. The
limits are designed as analog signals so that the limits can be changed during operation.
The absolute torque limits are available in both speed and torque control.
You can switch between the limits during operation with a binary signal. This can be
used to increase the torque during a heavy duty startup, for example.
How to parameterize absolute
torque limits …
Absolute torque limits are parameterized on page 8.1 of the Assistant (Figure 8-1).
Proceed as shown below:
• Parameterize the source of the switchover signal in D110. When the signal is low the
value from C330 torque limit is used. When the signal is high the value from C331
torque limit 2 is used.
• Go to page 8.1.1 to set the first torque limit.
