Yaskawa Z1000 AC Drive HVAC - Manual (Page 123)

Setting 3: Option Card
This setting requires entering the frequency reference via an option board plugged into connector CN5 on the drive control
board. Consult the option card manual for instructions on integrating the drive with the communication system.
Note: If the frequency reference source is set for Option PCB (b1-01 = 3), but an option board is not installed, an oPE05 Programming Error will
be displayed on the HOA keypad and the drive will not run.
n b1-02: Run Command Selection for AUTO Mode
Determines the Run command selection for AUTO mode.
No. Parameter Name Setting Range Default
b1-02 Run Command Selection for AUTO Mode 1 to 3 1
Setting 1: Control Circuit Terminal
This setting requires entering the Run command via the digital input terminals using one of following sequences:
• 2-Wire sequence 1:
Two inputs (FWD/Stop-REV/Stop). Set A1-03 to 2220 to initialize the drive and preset terminals S1 and S2 to these
functions. This is the default setting of the drive.
• 2-Wire sequence 2:
Two inputs (Start/Stop-FWD/REV).
• 3-Wire sequence:
Three inputs (Start-Stop-FWD/REV). Set A1-03 to 3330 to initialize the drive and preset terminals S1, S2, and S5 to these
functions.
Setting 2: Serial Communication (APOGEE FLN, BACnet, MEMOBUS/Modbus, Metasys N2)
This setting requires entering the Run command via serial communications by connecting the RS-422/RS-485 serial
communication cable to control terminals R+, R-, S+, and S- on the terminal block.
Setting 3: Option Card
This setting requires entering the Run command via the communication option board by plugging a communication option
board into the CN5 port on the control PCB. Refer to the option card manual for instructions on integrating the drive into the
communication system.
Note: If b1-02 is set to 3, but an option card is not installed in CN5, an oPE05 Programming Error will be displayed on the HOA keypad and the
drive will not run.
n b1-03: Stopping Method Selection
Selects how the drive stops the motor when the Run command is removed or when a Stop command is entered.
No. Parameter Name Setting Range Default
b1-03 Stopping Method Selection 0 to 3 1
Setting 0: Ramp to Stop
When the Run command is removed, the drive will decelerate the motor to stop. The deceleration rate is determined by the
active deceleration time. The default deceleration time is set to parameter C1-02.
When the output frequency falls below the level set in parameter b2-01, the drive will start DC injection or Short Circuit
Braking depending on the selected control mode. Refer to b2-01: DC Injection Braking Start Frequency on page 151 for
details.
Setting 1: Coast to Stop
When the Run command is removed, the drive will shut off its output and the motor will coast (uncontrolled deceleration) to
stop. The stopping time is determined by the inertia and the friction in the driven system.
