■
b1-02: Up/Down Command Selection
Determines he Up/Down command source in the REMOTE mode. Wire the motor so the elevator goes up when an Up
command is issued.
No.
b1-02
Setting 0: Operator
Allows the user to enter Up/Down commands from the digital operator. Use this setting when performing a test run only.
Setting 1: Control Circuit Terminal
Up/Down commands are issued from the control circuit terminals. This is the standard setting used in most elevator
applications.
Setting 2: MEMOBUS/Modbus Communications
This setting requires entering the Up/Down commands via serial communications by connecting the RS-485/422 serial
communication cable to control terminals R+, R-, S+, and S- on the removable terminal block. Refer to
Modbus Configuration on page 384
Setting 3: Option Card
This setting requires entering the Up/Down commands via the communication option card by plugging a communication
option card into the CN5-A port on the control board. 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-A, an oPE05 operator programming error will be displayed on the
digital operator and the drive will not run.
■
b1-03: Stopping Method Selection
Selects how the drive stops the motor when the Up/Down command is removed or when a Stop command is entered.
No.
b1-03
Setting 0: Ramp to stop
Ramps the motor to stop at the deceleration ramp set in C1-02. The actual time required for deceleration may vary by load
conditions (mechanical loss, inertia).
Setting 1: Coast to stop
The drive will shut off output to the motor and allow it to coast freely to stop when the Up/Down command is removed.
■
b1-06: Digital Input Reading
Defines how the digital inputs are read.
No.
b1-06
Setting 0: Read once
The state of a digital input is read once. If the state has changed, the input command is immediately processed. With this
setting the drive responds more quickly to digital inputs, but a noisy signal could cause erroneous operation.
Setting 1: Read twice
The state of a digital input is read twice. The input command is processed only if the state does not change during the
double reading. This reading process is slower than the "Read once" process, but it is more resistant to noisy signals.
