Check whether the signal allocation
has overlapped in the digital input
signal selection [0x2200] - [0x2208]
and the digital output signal selection
[0x2210] - [0x2213].
Set the parameter appropriately for the
operation conditions.
UD_VTG
(Low Voltage)
Main power
input voltage
abnormality
Check whether the main power
voltage is 134 Vac or higher.
Re-inspect the main power source.
Check whether the DC link voltage
[0x2605] is between 190 - 405 Vdc
while the main power is being
supplied.
Replace the drive.
Lowered power
voltage during
operation
Check the wiring status of the main
power.
Use a 3-phase voltage supply.
EMG
(Emergency Signal
Input)
EMG contact

This represents the state of
emergency pause by EMG contacts.
Check the settings of the wiring and
drive parameters (drive control input 1
[0x211F], digital input signal 1 setting
[0x2200] - digital input signal 16
setting [0x220F]).
Set the wiring and parameter for the
operation conditions.
