z Use the electromagnetic brake when the SON is from ON go to OFF or alarm occurs in the servo driver.
This parameter defines the delay time from the action (the BRK is OFF from DO terminals) of the
electromagnetic brake until excitation removal of the servomotor during the servomotor to be in static.
z The parameter should not be smaller than the delay time in which the machinery applies the brake. This
parameter will make the brake reliable and then turns off the servomotor excitation to guarantee against the
small displacement of the servomotor or depreciation of the work piece.
z The timing chart refers to 4.12.3 section.

z Use the electromagnetic brake when the SON is from ON go to OFF or alarm occurs in the servo driver.
This parameter defines the delay time from excitation removal of the servomotor until the action (the BRK is
OFF from DO terminals) of the electromagnetic brake during the servomotor to be in motion.
z This parameter will make the servomotor deceleration from high speed down to low speed and then applies
the brake to avoid damaging the brake.
z The actual action time will take the minimum value in both the parameter P167 and the time in which the
servomotor decelerates to the P168 value.
z The timing chart refers to 4.12.4 section.
