b1-16
n b1-17: Run Command at Power Up
Determines whether an external Run command that is active during power up will start the drive.
No.
b1-17
Setting 0: Run Command at Power Up Is Not Issued
Cycle the Run command to start the drive.
Note: For safety reasons, the drive is initially programmed not to accept a Run command at power up (b1-17 = 0). If a Run command is issued at
power up, the RUN indicator LED will flash quickly.
Setting 1: Run Command at Power Up Is Issued
If an external Run command is active when the drive is powered up, the drive will begin operating the motor once the internal
start up process is complete.
WARNING! Sudden Movement Hazard. If b1-17 is set to 1 and an external Run command is active during power up, the motor will begin
rotating as soon as the power is switched on. Proper precautions must be taken to ensure that the area around the motor is safe prior to
powering up the drive. Failure to comply may cause serious injury.

b2: DC Injection Braking and Short Circuit Braking

These parameters determine operation of the DC Injection Braking, Zero Speed Control, and Short Circuit Braking features.
n b2-01: DC Injection Braking Start Frequency
Active when "Ramp to Stop" is selected as the stopping method (b1-03 = 0).
No.
b2-01
The function triggered by parameter b2-01 depends on the control mode that has been selected.
V/f, V/f w/PG, and OLV (A1-02 = 0, 1, 2)
For these control modes, parameter b2-01 sets the starting frequency for DC Injection Braking at Stop. When the output
frequency falls below the setting of b2-01, DC Injection Braking is enabled for the time set in parameter b2-04.
Note: If b2-01 is set to a smaller value than parameter E1-09 (minimum frequency), then DC Injection Braking will begin as soon as the frequency
falls to the value set to E1-09.
CLV (A1-02 = 3)
Note: PM motor control modes are not available in A1000 HHP drive models.
For these control modes, parameter b2-01 sets the starting frequency for Zero Speed Control (not position lock) at stop. When
the output frequency falls below the setting of b2-01, Zero Speed Control is enabled for the time set in parameter b2-04 provided
b1-05 is set to 0.
