n b1-17: Run Command at Power Up
This parameter is used to determine whether an external Run command that is active during power up of the drive will start
the drive or not.
No.
b1-17
Setting 0: Run Command at Power Up is not Issued
The Run command has to be cycled to start the drive.
Note: For safety reasons, the drive is initially set up 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. Change parameter b1-17 to 1 if a Run command active at power up shall be accepted by the
drive.
Setting 1: Run Command and Power Up is Issued
An external Run command active during power up is issued and the drive starts to operate the motor as soon as it gets ready
for operation (i.e. 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

These parameters determine how the DC Injection Braking/Short Circuit Braking feature operates. Parameters involving the
starting frequency, current level, braking time are located here.
n b2-01: DC Injection Braking Start Frequency
Active when "Ramp to Stop" is selected as the stopping method (b1-03 = 0). Sets the starting frequency for:
• DC Injection Braking at stop in V/f and OLV control.
• Short Circuit Braking at stop in PM OLV control.
No.
b2-01
When the output frequency while ramping to stop drops below b2-01, the drive begins DC Injection/Short Circuit Braking in
order to completely stop the motor at the end of deceleration. If b2-01 < E1-09 (Minimum Frequency), then DC Injection/
Short Circuit Braking begins at the frequency set to E1-09.
No.
E1-09 Minimum Output Frequency
<1> The upper limit for the setting range is determined by E1-04.
