1.9 n: Special Adjustments
The n parameters handle a variety of specialized adjustments and functions, including
Hunting Prevention, ASR Control, High Slip Braking, resistance between motor lines, and
PM motor control functions.
◆
n1: Hunting Prevention
Hunting Prevention keeps the drive from hunting as a result of low inertia and operating
with light load. It is available in V/f Control only.
■
n1-01: Hunting Prevention Selection
Enables or disables the Hunting Prevention function.
Note:
This function is available only when using V/f Control. Hunting Prevention should
be disabled when drive response is need over suppressing motor oscillation. This
function can also be disabled without any problems in applications with high inertia
loads or relatively heavy loads.
Setting 0: Disabled
Setting 1: Enabled
■
n1-02: Hunting Prevention Gain Setting
Sets the gain for the Hunting Prevention Function.
Normally, n1-02 does not need to be changed, but adjustment may help under the following
conditions:
• If the motor vibrates while lightly loaded and n1-01 = 1, increase the gain by 0.1 until
vibration ceases.
• If the motor stalls while n1-01 = 1, decrease the gain by 0.1 until the stalling ceases.
■
n1-03: Hunting Prevention Time Constant
Determines how responsive the Hunting Prevention function is (affects the primary delay
time for Hunting Prevention).
