N2 Points

Point

Description

3-06:

Control Mode

This point allows the user to manipulate the control mode in which the drive is running. The
drive powers up and will remain in LOCAL Control Mode until the first override or release
command is sent to it. The drive will then switch to SERIAL Control Mode. This point can be
used to change the control mode back to LOCAL (0) for front panel manipulation. It can also
be used to change the control mode to REMOTE to control the drive from the terminal strip.
If this point is overridden with REMOTE (1), no overrides or releases will be recognized
except for the CONTROL MODE point until the drive is returned to SERIAL control mode. The
release of this parameter will return it to the value specified by Parameter 30 (CONTROL).

4.5 Binary Output (BO) Point Descriptions

Point

Description

4-01:

Clear Fault History

This history stores the last eight (8) faults that tripped the drive. These are viewable via
Analog Input Points 1-12 through 1-19. This history can be cleared by overriding Binary
Output Point 1 with a one (1). This will reset each of the eight fault blocks to a no fault
status. Once the fault history is cleared, this object will not reset itself to a zero state until
another fault is recorded in the history or until serial control is shut down.

4-02:

Start/Stop Drive

Allows the drive to be started and stopped through the serial link. The value of this object
should follow the current run status of the motor. It will reset itself to a zero state if the
drive is stopped, decelerating to a stop or in a fault condition. It will set itself to a set state
if the drive is started locally while serial control is disabled.

4-03:

Auto/Manual Select

This object controls the speed source from which the drive receives its command speed.

AUTO

If this point is set to Auto (0), then the drive will get its command speed from
the currently selected speed source on the terminal strip (i.e. speed pot, preset
speeds 1 - 4, etc. ...) or from the PID Setpoint if PID Mode is enabled.

MANUAL If this point is set to Manual (1), then the drive’s command speed will come

directly from the keypad. This selection is restricted by Parameter 28 (Keypad
Programming) which has four settings: AUTO, MANUAL, A/M LOC and A/M SPD.

AUTO

If parameter 28 is set to AUTO, then the drive can only get its
command speed from the source selected on the terminal strip or
from the PID setpoint.

MANUAL If parameter 28 is set to MANUAL, then the drive can only get its

operating speed from the keypad.
