# Once the operating command is given, then when the output frequency and output current reach the

setting level, the brake will be released after brake delay time.

# During the operation, if the frequency command is less than the brake releasing frequency, reset manually

frequency command to MAX (brake releasing frequency, brake holding frequency) to operate.

# Once the brake is released, it will not be held unless a stop command is give or certain errors are

occurred.

# Once the stop operating command is given, then when the output frequency or output current is lower than

the setting level, the brake holding operation will hold immediately the brake without delay time.

#To FWD brake releasing: Send operating command then set output frequency >= Pr02-34 and set output

current >=Pr02-33, delay Pr02-32 to release brake.

#To REV brake releasing: Send operating command then set output frequency >= Pr02-61 and set output

current >=Pr02-59, delay Pr02-32 to release brake.

#To FWD brake holding: Send stop operating command and set output frequency < Pr02-58 or set

output current < Pr02-57, release immediately the brake.
