Note 1) When the DC braking (DB) function is assigned by using the input terminal function 22 or 23,
it is normal if "" disappears when opening the circuit between the terminal and CC (or P24).

Remedies
 Close the ST-CC (or P24) circuit.
 Measure the main circuit supply voltage.
If the voltage is at a normal level, the
inverter requires repairing for fault.
 The inverter restarts automatically. Be
careful of the machine because it may
suddenly restart.
 Set the frequency setting signals at points
1 and 2 apart from each other.
 Press the STOP key again to clear the
trip.
 Press the STOP key for an emergency
stop.
To cancel the emergency stop, press any
other key.
 Check whether the setting is made
correctly.
 Press MODE key to exit the data group.
 The message goes off in several tens of
seconds if no problem occurs. Note 1)
 Lower the frequency free unit
magnification .
 To restart operation, reset power supply or
input an operation signal again.
 This function is cancelled, when
frequency reference reaches LL+0.2Hz or
operation command is OFF.
 Normal if the message disappears after a
while (several seconds to several tens of
seconds).
 Set the points to different values.
 Set the inclination of V/f to be flat.
