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 reference can be selected.
01
KEYPAD: Use the
L and M 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-5 (+) and
TB-2 (-).
04
4 - 20 mA:
The drive will respond to a 4-20 mA signal wired to TB-25 (+) and
TB-2 (-).
P06
RELAY OUTPUT
This selects the status indication for the normally open relay output at TB-16 and TB-17.
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).
