2.2 b: Application
b1-17: Run Command at Power Up
n
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 after 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.
u b2: DC Injection Braking
These parameters determine how the DC Injection Braking and Zero Speed Control operate.
b2-01: Zero Speed Level (DC Injection Braking Start Frequency)
n
Active when "Ramp to stop" is selected as the stopping method (b1-03 = 0).
No.
b2-01 Zero Speed Level (DC Injection Braking Start Frequency)
The function triggered by parameter b2-01 depends on the control mode that has been selected.
V/f and OLV (A1-02 = 0, 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.
Figure 2.10
Note: If b2-01 is set to a smaller value than E1-09 (Minimum Frequency), then DC Injection Braking will begin when the frequency
falls to the E1-09 value.
CLV (A1-02 = 3)
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.
Figure 2.11
Note: If b2-01 is set to a smaller value than E1-09 (Minimum Frequency), then Zero Speed Control begins at the frequency set to
E1-09.
