The motor will begin rotating immediately after the power is switched on. Take proper precautions to ensure the area around the motor is safe prior to powering up thedrive. Failure to comply may cause injury.Note: 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. For thedrive to issue the run command, change b1-17 = “1”.u b2: DC Injection BrakingThese parameters determine how the DC Injection Braking feature operates. Parameters involving the starting frequency, current level, braking time, andmotor pre-heat current level are located here.n b2-01: DC Injection Braking Start FrequencySets the frequency at which DC Injection Braking starts when “Ramp to Stop” is selected as the stopping method (b1-03 = 0). Set in Hz.No. Name Setting Range Defaultb2-01 DC Injection Braking Start Frequency 0.0 to 10.0 0.5Detailed DescriptionParameter b2-01 sets the output frequency at which the drive begins DC Injection during ramp to stop in order to lock the rotor of the motor and establishedthe end point of the ramp. If b2-01 < E1-09 (Minimum Frequency), then DC Injection begins at at the frequency set to E1-09.No. Name Setting Range DefaultE1-09 Minimum Output Frequency (FMIN) 0.0 to 400.0* Determined by A1-02 and C1-03. OLV for PM relies on E5-01.*The upper limit for the setting range is determined by E1-04. E5-01 determines the default value when using PM Open Loop Vector.b2-04b2-01DC Injection Brakingstart frequencyoutputfrequency braking timeFigure 5.8 DC Injection Braking during Decelerationn b2-02: DC Injection Braking CurrentSets the DC Injection Braking current as a percentage of the drive rated current. If set to larger than 50%, the carrier frequency is automatically reducedto 1 kHz.No. Parameter Name Setting Range Defaultb2-02 DC Injection Braking Current 0 to 75 50Detailed DescriptionThe level of DC Injection Braking current affects the strength of the magnetic field attempting to lock the motor shaft. Increasing the level of current willincrease the amount of heat generated by the motor windings, and should only be increased to the level necessary to hold the motor shaft. DC Injectioncurrent is set as a percentage of drive rated output current. Find the drive rated output current by looking at the information listed on the drive nameplate.n b2-03: DC Injection Braking Time at StartSets the time of DC Injection Braking at start in units of 0.01 s, and is used to stop a coasting motor. Disabled when set to 0.00 s.5.2 b: Setup116 YASKAWA ELECTRIC SIEP C710606 18A YASKAWA AC Drive – V1000 Technical Manual (Preliminary)
