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 SPEED SOURCE
This selects the speed reference source when the drive is in STANDARD speed mode. The following
speed references can be selected:
01 KEYPAD: Use the p and q buttons to scroll to the desired speed.
02 PRESET SPEED #1: The drive will operate at the frequency set into Parameter 31.
03 0 - 10 VDC: The drive will respond to a 0-10 VDC 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.
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.
05 FAULT LOCKOUT: Closes when input power is applied. Opens if three restart attempts are
unsuccessful, or if input power is removed.
06 AT SET SPEED: Closes if the drive is within + 0.5 Hz of the speed setpoint.
07 ABOVE PRESET SPEED #3: Closes if the output frequency exceeds the PRESET SPEED #3 setting.
Opens if the output frequency is equal to or less than PRESET SPEED #3 (Parameter 33).
08 CURRENT LIMIT: Closes if the output current exceeds the CURRENT LIMIT setting. Opens if the
output current is equal to or less than CURRENT LIMIT (see Parameter 25).
09 AUTOMATIC SPEED MODE: Closes if an AUTOMATIC (terminal strip) speed reference is active.
Opens if a STANDARD (Parameter 5) speed reference is active.
10 REVERSE: Closes when reverse rotation is active. Opens when forward rotation is active. (see
Parameter 17 - ROTATION DIRECTION).
