WARNING!
Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before applying
power to the drive. Failure to comply could result in death or serious injury from moving equipment.
WARNING!
Sudden Movement Hazard. The drive may start unexpectedly in reverse direction after power up if it is wired for 3-Wire sequence
but set up for 2-Wire sequence (default). Make sure b1-17 is set to “0” (drive does not accept a Run command active at power up). When
initializing the drive use 3-Wire initialization. Failure to comply could result in death or serious injury from moving equipment.
Setting 2: External Reference 1/2 Selection
Switches between two different sources of Run Commands and Frequency References. When multi-function digital input
selection 2 (Ext Ref Sel) is programmed, the Run Command and Frequency Reference source can be switched between External
Reference 1 (b1-01/b1-02) and External Reference 2 (b1-15/b1-16) if the drive is in AUTO mode.
Settings 3 to 5: Multi-Step Speed Reference 1 to 3
Switches multi-step speed frequency references d1-01 to d1-08 by digital inputs.
Setting 6: Jog Reference Selection
The Jog frequency set in parameter d1-17 becomes the frequency reference when the input terminal closes.
Setting 7: Accel/Decel Time Selection 1
Switches between accel/decel times 1 (C1-01 and C1-02) and 2 (C1-03 and C1-04).
Refer to C1-01 to C1-04: Accel, Decel
Settings 8 and 9: Baseblock Command (N.O., N.C.)
When the drive receives a baseblock command, the output transistors stop switching, the motor coasts to stop, and a bb alarm
flashes on the digital operator to indicate baseblock. When baseblock ends while a Run command is active, the drive performs
Speed Search to restart the motor.

WARNING!
Sudden Movement Hazard. When using a mechanical holding brake with the drive in a lifting application, close the brake when
the drive output is cut off by a baseblock command triggered by one of the input terminals. Failure to comply will result in a slipping load
from the motor suddenly coasting when the baseblock command is entered and may cause serious injury or death.

Figure 5.41 Baseblock Operation During Run
Setting A: Accel/Decel Ramp Hold
When the digital input programmed for the Accel/decel ramp hold function closes, the drive locks (holds) the output frequency.
Acceleration or deceleration resumes when the input is reopened.
If the Accel/decel ramp hold function is enabled (d4-01 = 1), the drive saves the output frequency to memory when the Ramp
Hold input is closed. When the drive is restarted after stop or after power supply interruption, the saved output frequency
becomes the frequency reference (provided that the Accel/decel ramp hold input is still closed).
Setting B: Drive Overheat Alarm (oH2)
Triggers an oH2 alarm when the contact closes. Drive operation is not affected because this is an alarm.
