Chapter 9 Parameter Descriptions
Sets the response time of slip compensation.
Parameters in the Slip Comp Group (121...123) are used to enable and tune the
slip compensation regulator. To allow the slip compensation regulator to control
drive operation, Speed Mode (80) must be set to 1 (Slip Comp).
Displays the present amount of adjustment being applied as slip compensation.
Selects specific features of the PI regulator.

Bit 0 – Excl Mode (Exclusive Mode)
• Enabled = Selects speed regulation.
• Disabled = Selects trim regulation.
Bit 1 – Invert Error
• Enables/disables the option to invert the sign of the PI error signal.
Enabling this feature creates a decrease in output for an increasing error
and an increase in output for a decreasing error.
Bit 2 – Preload Mode
• Enabled = Initializes the PI integrator to the commanded speed while the
PI is disabled.
• Disabled = The PI integrator is loaded with the PI Pre-load (133) while
the PI is disabled.
