OPERATION

FDT-3: Select
4_FDT-3
for any relay output in
[IO-47] ~ [IO-49] . It requires two following
parameters for setup:
FDT-3 Frequency [IO-54]: VFD will acti -
vate a selected relay during acceleration
between frequencies
[IO-54] + 0.5Hz and
[IO-54]
+
[IO-55]
. VFD will activate relay
during deceleration between frequencies
[IO-54]
+
[IO-55]
-0.5Hz and
[IO-54]
.
FDT-3 Bandwidth [IO-55]: Provides offset
from
[IO-54]
to deactivate relay during
acceleration.
FDT-4: VFD will activate selected relay output when frequency is less than
FDT-4/5 Setting [IO-57] value. When frequency is greater than [IO-57] value, VFD will deacti -
vate relay output.
FDT-5: VFD will activate selected relay output when frequency is greater than
FDT-4/5 Setting [IO-57]
value. When frequency is less than
[IO-57]
value, VFD will deactivate
relay output.
FDT-4/5 Setting [IO-57]: The common frequency parameter for both FDT-4 and FDT-5
functions.
Scheduling
The X-Drive allows the user to create up to four scheduled VFD control events (Programs) in Auto mode.
Each Program can activate one of three event types:
•
Scheduled Start/Stop (VFD Run): This selection activates start and stop commands in Auto mode. If
Auto Run Command [SET-08]
is set to Digital Input with run command present or to
4_Ext HOA in Auto
, the VFD
will start only when the VFD Run Program reaches On Time, and it will stop when OFF Time is reached.
If during scheduled run HOA is changed to OFF or run command is removed, VFD will stop.
• During a scheduled event, the VFD can run the motor with selected speed control (analog, PID,
Comms) or with preset speeds
• Switch to preset frequency: During scheduled event VFD will run motor with selected preset fre -
quency, set in
[VFD-04] ~ [VFD-06],
when running in Auto mode without PID control.
• Switch to preset setpoint (S-Point): During scheduled event VFD will change motor control to the
selected preset setpoint, set in
[ADV-74] ~ [ADV-76],
when running in Auto mode with PID control.
NOTE: Scheduled Start/Stop and switch to PID preset Setpoint (PID Preset S-Point) commands work in
Multi-VFD setup. In this instance, preset frequency commands will be ignored.
NOTE: In Multi-VFD mode, be sure to program all VFDs with identical scheduling setup and synchronized
clock settings
