Example 2: Remote Sequence (2-Wire) & Remote Reference
(4 – 20 mA)
- viii -
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 drive
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 Ext Fault”.
• Frequency reference is proportional to the signal level at Terminal FI. 4mA = 0 Hz, 12mA = 30 Hz, &
20mA = 60 Hz.
• If the LOCAL / REMOTE key is pressed, the drive will behave the same as illustrated in Example 1.

Parameter Display Description
n001 Password
8
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.
n001 Password
3
After doing the reset above, the password parameter returned to a
1. Change it to a 3 to get access to all parameters in the drive.
n043 Analog Input Sel
FV=AUX FI=MSTR
This parameter sets terminal FI to be the frequency reference.
