i.5 Start-Up Programming and Operation
Setting 6: AUTOKey + Term
When b1-02/b1-16 = 6, the AUTO key puts the drive into AUTO mode and the terminal programmed for Run (H1-oo = 40,
41, or 42) acts as the External Run command.
Note: Available in drive software versions PRG: 8552 and later.
Note: 1. Setting available in drive software versions PRG: 8552 and later.
2. Setting not available in drive models 4A0930 and 4A1200.
Setting 7: AUTOKey + Serial
When b1-02/b1-16 = 7, the AUTO key puts the drive into AUTO mode and the Serial Run command (register 0001) acts as
the External Run command.
Note: 1. Setting available in drive software versions PRG: 8552 and later.
2. Setting not available in drive models 4A0930 and 4A1200.
Setting 8: AUTOKey + Option
When b1-02/b1-16 = 8, the AUTO key puts the drive into AUTO mode and the Option Card Run command acts as the External
Run command.
Note: 1. Setting available in drive software versions PRG: 8552 and later.
2. Setting not available in drive models 4A0930 and 4A1200.
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.
Note: Parameter b1-11, Run Delay at Stop (Back Spin Timer), is effective for all stopping methods (b1-03 = 0 to 3), not only Coast to Stop w/
Timer (b1-03 =3).
No.
b1-03
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, Zero Speed Control,
or Short Circuit Braking.
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.
Setting 2: DC Injection Braking to Stop
When the Run command is removed, the drive will enter baseblock (turn off its output) for the minimum baseblock time
(L2-03). When the minimum baseblock time has expired, the drive will inject the amount DC Injection Braking is set in
parameter b2-02 into the motor windings to brake the motor. The stopping time in DC Injection Braking to Stop is significantly
faster compared to Coast to Stop.
DC Injection Braking time is determined by the value set to b2-04 and the output frequency at the time the Run command is
removed. It can be calculated by:
Setting 3: Coast to Stop with Timer (Used for Back Spin Control on Vertical Turbine Pumps)
When the Run command is removed, the drive coasts to a stop. If parameter b1-11 is set to zero, the coast-timer (Run Delay
at Stop) becomes a value determined by a combination of output frequency and the C1-02 parameter. However, if b1-11 is set
greater than zero, the Run Delay at Stop timer is set to b1-11. If the Run command is re-issued during the Run Delay at Stop
timer time, the drive WILL restart when the timer expires without the need to re-cycle the Run command. The Run Delay at
Stop timer will operate for both AUTO Mode and HAND Mode. The Run Delay at Stop timer will still operate when the drive
goes to sleep and then wakes up. During the Run Delay at Stop timer execution, the HOA keypad will display the alarm
"WrUn". Both Alarm and Run indicators will blink while the drive waits to execute the Run command.
The wait time t is determined by the output frequency when the Run command is removed and by the active deceleration time.
n b3-01: Speed Search Selection at Start
Determines if Speed Search is automatically performed when a Run command is issued.
No.
