P04 STOP METHOD

01 COAST TO STOP: When a STOP command is given, the drive shuts off the

output to the motor, allowing it to coast freely to a stop.

02 COAST WITH DC BRAKE: When a stop command is given, the drive will

activate DC braking (after a delay of up to 2 seconds, depending on frequency)

to help decelerate the load. Refer to Parameters: 21 - DC BRAKE TIME, and

22 - DC BRAKE VOLTAGE.

03 RAMP TO STOP: When a stop command is given, the drive will decelerate the

motor to a stop at the rate determined by Parameter 20 - DECELERATION

TIME.

04 RAMP WITH DC BRAKE: When a stop command is given, the drive will

decelerate the motor down to 0.2 Hz (at the rate set by Parameter 20 -

DECELERATION TIME) and then activate DC braking according to the settings

of Parameters 21 - DC BRAKE TIME and 22 - DC BRAKE VOLTAGE. This is

used to bring the load to a ﬁnal stop, as the motor may still be turning slightly

after the drive stops.

P05 STANDARD REFERENCE SOURCE

This selects the default speed or torque reference source for the drive if another reference

is not selected using TB-13A, 13B, 13C, or 13D, or Parameter 07 - BIPOLAR REFERENCE

SELECTION. The following reference sources can be selected:

01 KEYPAD: Use the s and t buttons to scroll to the desired speed/torque.

02 PRESET SPEED #1: The drive will operate at frequency set in Parameter 31.

03 0-10 VDC: The drive will respond to a 0-10VDC signal wired to TB-2 and TB-5.

04 4-20 mA: The drive will respond to a 4-20 mA signal wired to TB-2 and TB-25.

NOTE

When the drive is in VECTOR TORQUE mode (see Parameter 80), setting

02 (PRESET #1) will become the same as setting 01 (KEYPAD). In torque

mode, preset speeds cannot be used as torque references.

P06 TB-14 OPEN COLLECTOR OUTPUT

This selects the status indication for the open-collector output at TB-14. The terms “open”

and “close” refer to the state of the internal transistor that activates the circuit. When the

transistor is “closed”, TB-14 is at the same potential as TB-2, allowing current to ﬂow.

01 NONE: Disables the open-collector output.

02 RUN: Closes upon a START command. Opens if the drive is in a STOP state,

the drive faults, or input power is removed. DC braking is considered a STOP

state.

03 FAULT: Closes if there is no fault condition. Opens if the drive faults, or input

power is removed.

04 INVERSE FAULT: Closes if the drive faults. Opens if there is no fault condition.
