Example 2: Remote Sequence (2-Wire) & Remote Reference
(4 – 20 mA)
This configuration is used when the start & stop signals and the frequency reference come from a remote
source, such as a PLC. It can also be used with a maintained switch when it is desirable to have the
D
rive
restart on restoration of power. It should not be used where safety of attending personnel might be threatened
by a restart.
OPERATION:
• Close (K1) to Run Forward.
• Close (K2) to Run Reverse.
• If both (K1) & (K2) are closed, the drive stops and displays the
error message: “EF”.
• Frequency reference is proportional to the signal level at
Terminal FI. 4mA = 0 Hz, 12mA = 30 Hz, & 20mA = 60 Hz.
• If the drive is put in the “Local” mode using the LO/RE quick
start LED, the drive will behave the same as illustrated in
Example 1.

Parameter Display
Description
n01
Password
10
The drive will perform a 2-wire reset.
CAUTION: Setting this value will reset all parameters to their
original factory settings (all previous adjustments will be lost)
When the drive completes the reset, this parameter returns to a
value of 1.
n03
3
This parameter sets terminal FR to be a 4-20mA input. NOTE:
Switch (SW8) must be closed (“on”). Prying off the cover using a
small screwdriver as shown in the diagram above allows access to
switch (SW8).
n32 Set
Motor
FLA
Enter the motor’s full load amps (as shown on the motor
nameplate).
