No. Parameter Name
b1-08 Run Command Selection during Program*
*"Programming mode" refers to when the drive is in the Setup mode, the Parameter Settings mode, performing Auto-Tuning, or the user is viewing the
Verify Menu.
Setting 7: DC Bus Undervoltage
Output closes whenever the main circuit DC bus voltage or control circuit power supply drop below their respective trip level. The undervoltage trip level
is determined by L2-05. An open soft charge contactor answer back signal will also cause the DC Bus Undervoltage output to close.

No.
L2-05
*1. Default setting is determined by the drive capacity set to o2-04.
*2. This value is for a 200 V class drive. Double this value when using a 400 V class unit.
Setting 8: During Baseblock
Output closes to indicate that the drive is in baseblocked state. While baseblock is executed, output transistors are prevented from firing.
Status
Open
Closed
Setting 9: Operator Reference
Output closes when the frequency reference is being sourced from the operator.
Status
Open
Closed
Setting A: LOCAL/REMOTE Operation
Output closes when the Run command is being sourced from the operator.
Status
Open
Closed
Setting B: Torque Detection 1, N.O.
Setting 17: Torque Detection 1, N.C.
Setting 18: Torque Detection 2, N.O.
Setting 19: Torque Detection 2, N.C.
Theses functions tie a digital output to the overtorque/undertorque sensing capabilities of the drive. The digital output switches whenever the output current
falls above or below the specified levels for the specified time period.
Select the type of torque detection and assign it to one of the multi-function output terminals (H2-01 to H2-03 = B, 17, 18, 19). Set the torque detection
level to L6-01 for Torque Detection 1 or to L6-04 for Torque Detection 2.
Setting Status
B Closed
17 Open
18 Closed
19 Open
Note: The torque detection function has a built-in hysteresis of 10% of the drive rated output current. The torque detection function is based on 100% of the drive rated output current
when using V/f Control or PM Open Loop Vector. In general Open Loop Vector Control, torque detection is based on 100% of the motor rated torque.
Parameters related to torque detection appear in the table below.

Drive ready: In the Drive Mode with no fault situation. Drive can begin running the motor.
0: Disabled - Run command accepted only in the operation menu.
1: Enabled - Run command accepted in all menus (except when b1-02 = 0).
2: Operation not possible. Cannot enter the Programming mode* because the Programming Mode
cannot be accessed during run.
