Adjustable Frequency Drives
Stop Spd Gain
P1-07= 0
P1-07 Stop Speed Gain Q Q Q Q
Setting Range: 0 to 10
Factory Default: 0
This parameter sets the frequency threshold where the positioning algorithm takes control of stopping the drive. It is
based on a minimum threshold of 4.096 Hz with a 1 setting. The minimum threshold is multiplied by this value to achieve
a maximum threshold of 40.96 Hz. This value also controls the rate of deceleration. The positioning algorithm will bring
the drive to a stop in the orient position within 2 revolutions after initiated.
Spindle Ratio Num
P1-08= 1
P1-08 Spindle Ratio Numerator Q Q Q Q
Setting Range: 1 to 10
Factory Default: 1
This parameter and P1-09 (Spindle Ratio Div) must be set to the proper spindle to motor ratio. This ratio is required for
the positioning to function properly.
Spindle Ratio Div
P1-09= 1
P1-09 Spindle Ratio Divisor Q Q Q Q
Setting Range: 1 to 10
Factory Default: 1
This parameter and P1-08 (Spindle Ratio Num) must be set to the proper spindle to motor ratio. This ratio is required for
the positioning to function properly.
