5.2 b: Application n b1-04: Reverse Operation Selection For some applications, reverse motor rotation is not appropriate and may even cause problems (e.g., air handling units, pumps, etc.). Setting parameter b1-04 to 1 instructs the drive to ignore any Reverse run commands. Setting 0: Reverse Operation Enabled Possible to operate the motor in both forward and reverse directions. Setting 1: Reverse Operation Disabled Drive disregards a Reverse run command or a negative frequency reference. n b1-07:
LOCAL/REMOTE Run Selection The drive has the following three separate control sources that can be switched using digital inputs or the LO/RE key on the digital operator (for details Refer to Setting 1: LOCAL/REMOTE Selection on page 91 and Refer to Setting 2: Serial Communication Reference Selection on page 91 ): • LOCAL - The digital operator is used to set the reference and the Run command. • REMOTE - The settings of b1-01 and b1-02 determine where the frequency reference and Run command are input from. • Serial Communications by MEMOBUS/Modbus.
When switching from LOCAL to REMOTE, or to serial communication , the Run command may already be present at the location the source was switched to. Parameter b1-07 can be used to determine how the Run command is treated in this case. Setting 0: Run Command Must Be Cycled If the Run command is issued differently in the old and new control source (e.g. old - terminals, new - serial communications) and it is active at the new source when switching takes place, the drive will either not start or it will stop if it was running before. The Run command has to be cycled to start from the new control source. Setting 1:
Continue Running If the Run command is active at the new control source, the drive starts or continues running. There is no need to cycle the Run command. WARNING! The drive may start unexpectedly if switching control sources when b1-07 = 1. Clear all personnel away from rotating machinery and electrical connections prior to switching control sources. Failure to comply may cause death or serious injury. n b1-08: Run Command Selection while in Programming Mode As a safety precaution, the drive will not normally respond to a Run input when the digital operator is being used to adjust parameters in the Programming Mode (Verify Menu, Setup Mode, Parameter Settings Mode).
If required by the application b1-08 can be used to changed this functionality. Parameter Details 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. 5 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. Setting 0: Standard Phase Order Setting 1: Switched Phase Order SIEP C710606 33A OYMC AC Drive – J1000 User Manual 75 No.
