P.007 Terminal Strip Digital Inputs Configure (continued)
FWD/REV
FWD/REV allows you to select between forward or reverse operation. If the input is
closed, this function will invert the selected speed reference. For example, if the
selected speed reference value is negative (<0) and the FWD/REV input is closed, the
resulting speed reference will be positive.
The digital input for FWD/REV is active only if the control source is remote.
RAMP 1/2
RAMP 1/2 allows you to select one of two paired acceleration/deceleration rates.
RAMP 1 uses acceleration or deceleration rates based on P.001/P.002
(Accel Time 1/Decel Time 1). RAMP 2 uses acceleration or deceleration rates based
on P.017/P.018 (Accel Time 2/Decel Time 2).
The digital input for RAMP 1/2 is always active regardless of the control source.
REM/LOC
REM/LOC allows you to switch from terminal strip control to local keypad control. The
drive must be stopped in order to do this. (Note that if an OIM is connected, REM/LOC
will switch control from the terminal strip to the OIM, not to the local keypad.)
The digital input for REM/LOC is active only if the control source is remote.
The following example shows how the REM/LOC input can be used:
REM/LOC Input Example
Assume the drive is stopped and started using an external two-wire control signal.
The drive’s control source is the terminal strip (P.000 = rE), and a START command
is given. The REM/LOC option (P.007 = 2) is selected so that an external REM/LOC
switch switches the drive from REMOTE to LOCAL or from LOCAL to REMOTE.
This external switch is in the REMOTE position.
The following happens:
1. The STOP/RESET key is pressed, and the motor stops.
2. LOCAL is selected using the externally-wired REM/LOC switch.
3. Control of the drive is done locally through the keypad (or through the OIM, if
connected). (This could be for troubleshooting purposes, or for viewing/adjusting
parameter values.)
4. The REM/LOC switch is switched back to the REMOTE position. The drive runs
immediately because there is already an asserted remote start signal.
5. The drive is now being controlled by the remote control source.
