[12] Er1 Memory error
Problem Error occurred in writing the data to the memory in the drive.
Possible Causes What to Check and Suggested Measures
(1) Power supply turned off
while drive was writing
data (especially initial-
izing data), and residual
control circuit voltage
was not high enough to
enable writing of data.
CHECK
Check whether pressing the key resets the alarm after the function code data are initialized by setting
the data for function code H03 to 1.
SUGGESTED ACTIONS
– Return the initialized function code data to their previous settings, then restart the operation.
(2) High intensity noise was
applied to the drive while
data (especially initial-
izing data) was being
written.
CHECK
Check if appropriate noise control measures have been implemented (e.g. correct grounding and routing
of control and main circuit wires). Alternatively, perform the same check as described in (1) above.
SUGGESTED ACTIONS
– Improve noise control. Alternatively, return the initialized function code data to their previous settings,
then restart the operation.
(3) The CPU did not operate
normally.
CHECK
Initialize the function code data by setting H03 to 1, then reset the alarm by pressing the key and
check that the alarm is triggered.
SUGGESTED ACTIONS
– Replace malfunctioning printed circuit board (PCB).
[13] Er2 Remote keypad communications error
Problem A communications error occurred between the remote keypad and the drive.
Possible Causes What to Check and Suggested Measures
(1) Break in the communica-
tions cable or poor
contact.
CHECK
Check continuity of the cable, contacts and connections.
SUGGESTED ACTIONS
– Replace the cable.
(2) High intensity noise was
applied to the drive.
CHECK
Check if appropriate noise control measures have been implemented (e.g. correct grounding and routing
of control and main circuit wires).
SUGGESTED ACTIONS
– Improve noise control.
(3) The remote keypad
malfunctioned.
CHECK
Check that alarm Er2 does not occur if you connect another remote keypad to the drive.
SUGGESTED ACTIONS
– Replace the remote keypad
(4) The RS485 communica-
tions card malfunctioned.
CHECK
Check that alarm Er2 does not occur even if you connect another remote keypad to the drive.
SUGGESTED ACTIONS
– Replace the card.
