Setting 77: ASR Gain Switch
Switches the ASR gain between the values set in C5-01 and C5-03. The gain set to C5-03 is enabled when the terminal is
closed, and C5-01 is enabled when the terminal opens again. Refer to
C5: Automatic Speed Regulator (ASR) on
for a more detailed description.
Setting 78: External Torque Reference Polarity Inversion
Reverses the direction of the torque reference when the terminal closes. Refer to
d5: Torque Control on page 149
and
Setting the Torque Reference, Speed Limit, and Torque Compensation Values on page 150
for details.

terminal is closed.
• Decelerates (decreases the bias) while Down 2 is
closed.
• Holds output frequency (holds the bias) when no
Up 2 or Down 2 input or both active.
• Resets the bias when the reference changes.

• When the Up 2 is enabled, drive accelerates up to
the frequency reference plus d4-03 (bias is
increased for d4-03).
• When Down 2 is enabled, drive decelerates down
to the frequency reference minus d4-03 (bias is
decreased for d4-03).
• Holds output frequency (holds the bias) when no
Up 2 or Down 2 input or both active.
• Resets the bias when the reference changes.

• If the frequency reference changes for more than
d4-07 during accel/decel, bias value is held until the
output frequency meets the reference (speed agree).

If the bias is constant for 5 s, it is
saved to parameter d4-06. The

overwritten, so only the bias is
saved.
