ABB ACS580 - Limits

46 Settings, I/O and diagnostics on the control panel
The table below provides detailed information about the available setting items in the
Ramps menu.
 Limits
Use the Limits submenu to set the allowed operating range. This function is intended
to protect the motor, connected hardware and mechanics. The drive stays within
these limits, no matter what reference value it gets.

Stop mode: Sets how the drive stops the motor.
21.03 Stop mode
Use two ramp sets Sets the use of a second acceleration/deceleration
ramp set. If unselected, only one ramp set is used.
Note that if this selection is not d, the selection
below are not available.
Activate ramp set 2: To switch ramp sets, you can either:
• use a digital input (low = set 1; high = set 2), or
• automatically switch to set 2 above a certain
frequency/speed.
