B2: Dc Injection Braking - YASKAWA J1000 Technical Manual

No.
b1-08 Run Command Selection while in Programming Mode
Setting 0: Disabled
A Run command is not accepted while the digital operator is in Programming Mode.
Setting 1: Enabled
A Run command is accepted in any digital operator mode.
Setting 2: Prohibit Programming During Run
It is not possible to enter the Programming Mode as long as the drive output is active.
n b1-14: Phase Order Selection
Sets the phase order for drive output terminals U/T1, V/T2, and W/T3.
No.
b1-14
Setting 0: Standard Phase Order
Setting 1: Switched Phase Order
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 feature operates. Parameters involving the starting frequency,
current level, braking time are located here.
n
b2-02: DC Injection Braking Current
Sets the DC Injection Braking current as a percentage of the drive rated current. If set to larger than 50%, the carrier frequency
is automatically reduced to 1 kHz.
No.
b2-02
The level of DC Injection Braking current affects the strength of the magnetic field attempting to lock the motor shaft.
Increasing the current level will increase the amount of heat generated by the motor windings. This parameter should only be
increased to the level necessary to hold the motor shaft.
n b2-03: DC Injection Braking Time at Start
Sets the time of DC Injection Braking at start. It can be used to stop a coasting motor before restarting it or to apply a braking
torque at start. Disabled when set to 0.00 s.
