Multi-Function Input Terminal Function Settings (P3.03~P3.16) (continued)
Setting: Function Function Description
26: Emergency Stop EF1
(Coast stop) (EF1 error)
When contact is ON, the drive will execute emergency stop and display EF1 on
the keypad� The motor stays in the free run until the error is cleared (terminal’s
status is back to normal)� Only after pressing RESET (EF: External Fault), the
motor can continue to run� EF1 Fault is recorded in the error log�

27: Signal Confirmation for
Y-connection
When the control mode is V/Hz (P2�11=0) and the contact is ON, the drive will
operate by following the 1st V/Hz� The following parameters must also be
configured P2�20~P2�22, and two digital outputs (P3�17~P3�31) must be set to
29 and 30�
28: Signal Confirmation for Delta
connection
When the control mode is V/Hz (P2�11=0) and the contact is ON, the drive will
operate by following the 2nd V/Hz� The following parameters must also be
configured P2�20~P2�22, and two digital outputs (P3�17~P3�31) must be set to
29 and 30�
29: Disable EEPROM Write
When this contact is ON, write to EEPROM is disabled� The modified values
changed while this contact is on will revert back to the old values after restarting
the drive� (When input is ON, any values that are modified will not be retained
when power is cycled)
The RPR instruction in the PLC will not affect the EEPROM�
The WPR instruction will contribute to the 10
9
maximum life time EEPROM
writes to the FRAM memory in the drive�
30: Forced Coast Stop When this contact is ON during an operation, the drive will coast to stop�
31: Hand Contact for HOA Control
W hen controlling the drive using the standard HOA (Hand/Off/Auto) function,
settings 31 & 32 should be used together� When these multi-function input
terminals are both on or both off, the drive executes a STOP command�
That means when switching Hand to Auto or Auto to Hand the switch
configuration must pass through a Stop state causing the drive to always stop
when changing modes�
Lo cal/Remote buttons on the keypad and MFI setting 33 will not be operational
when digital inputs are configured for 31 & 32�
M FI settings 31 & 32 have priority over P3�58 settings�
Th e digital keypad will display the drive’s status (“HAND,” “OFF,” ”AUTO”) in the
upper right corner of the keypad, depending on what control mode the drive
is in�
P3 �57 contains additional behavior settings when switching from Auto to Hand�
DI1 = 31
DI2 = 32
(DI2, DI1) = 00 OFF Off
(DI2, DI1) = 01 HAND Follows LOCAL source (P3�01 & P4�01)
(DI2, DI1) = 10 AUTO Follows REMOTE source (P3�00 & P4�00)
(DI2, DI1) = 11 OFF Off
32: Auto Contact for HOA Control
33� LOCAL/REMOTE Selection
DI=0: (Switches to REMOTE source, P3�00 & P4�00)
DI=1: (Switches to LOCAL source, P3�01 & P4�01)
If another MFI is set to 31 or 32, then this input will be ignored�
This function is enabled when P3�58 is not set to 0�
Keypad “LOCAL” and “REMOTE” buttons will be disabled�
Th e digital keypad will display the drive’s states (“LOC”,”REM”) in the upper right
corner of the keypad�
MFO setting 24 will indicate the position of this function�
