5.2 b: Application
■
b1-08: Up/Down Command Selection while in Programming Mode
As a safety precaution, the drive will not normally respond to an Up/Down command input when the digital operator is
being used to adjust parameters in the Programming Mode (Verify Menu, Setup Mode, Parameter Settings Mode, and
Auto-Tuning Mode). If required by the application, set b1-08 to allow the drive to run while in the Programming Mode.
No.
b1-08
Setting 0: Disabled
An Up/Down command is not accepted while the digital operator is in the Programming Mode.
Setting 1: Enabled
An Up/Down 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. The Programming Mode cannot be
displayed during Run.
■
b1-14: Phase Order Selection
Sets the phase order for drive output terminals U/T1, V/T2, and W/T3. Switching motor phases will reverse the direction
of the motor. Use this parameter to switch the direction of the Up and Down commands.
No.
b1-14
Setting 0: Standard phase order (U-V-W)
Setting 1: Switched phase order (U-W-V)
Note: 1. If using a closed loop control mode such as CLV (A1-02 = 3) or CLV/PM (A1-02 = 7) and parameter b1-14 is changed, be sure to also
change the direction of the motor encoder (F1-05) to match the direction of the Up and Down commands.
2. If CLV/PM is used, also perform encoder offset Auto-Tuning.

■
b2-08: Magnetic Flux Compensation Value
Sets the magnetic flux compensation at start as a percentage of the no-load current value (E2-03). This function allows for
the development of more flux to facilitate starting machines that require high starting torque or motors with a large rotor
time constant.
No.
b2-08
When an Up/Down command is issued, the DC current level injected into the motor changes linearly from the level set to
b2-08 to the level set to E2-03 within the time set to b2-03.
