P21 DC Brake Delay CFN 20
LED Display LCD Display
Range 0.1 – 3.0 Seconds (Default 0.2)
Description When the Stop Mode (P15, CFN 14) is set to "DC brake", the DC Brake Delay time is the time delay between
when a stop is commanded and the DC braking current is applied to the motor. This delay allows the residual
magnetic field and motor counter EMF to decay before applying the DC braking current. If a large surge of
current is detected when DC braking is first engaged increase the delay time. If the delay before the braking action
begins is too long then decrease the delay time. In general, low horsepower motors can utilize shorter delays while
large horsepower motor may require longer delays.

P22 Initial Motor Current 2 CFN 06
LED Display LCD Display
Range 50 – 600 % of FLA (Default 100%)
Description The Initial Current 2 parameter is set as a percentage of the Motor FLA (P1 / QST 01) parameter setting when
the second ramp is active. Refer to the Initial Current 1 (P6 / CFN 03) parameter on page 79 for description of
operation.

LED Display LCD Display
Range 100 – 800 % of FLA (Default 600%)
Description The Maximum Current 2 parameter is set as a percentage of the Motor FLA (P1 / QST 01) parameter setting,
when the second ramp is active. Refer to the Maximum Current 1 (P7 / CFN 04) parameter on page 80 for
description of operation.
