Drive Overheat Warning
Drive Overheat Warning
input via a multi-function
input terminal (S1 to S7 )
when E1-口口= 40
An overheat warning in the
drive was triggered by an
external device
1. Search the device which caused the
overheat warning. Remove the cause
of the problem.
2. Reset Drive Overheat Warning input
at the assigned multi-function input
terminal (S1 to S7)
HCA
Current Alarm
Drive current exceeded the
level of over current
warning (150% of the rated
current)
1. The load is too heavy
2. Deceleration and
acceleration times are too
short
3.The drive is attempting to
run a motor greater than the
maximum allowable capacity,
or a special-purpose motor is
being used
4.The current level went up
because of Speed Search while
attempting to perform a fault
restart or after a momentary
power loss
1. Reduce the load or use a drive of
higher rating
2. Calculate the torque required during
acceleration and the inertia
»Take the following steps if the torque
level is not right for the load
· Increase the settings for acceleration
and deceleration time (C1-00 to C1-07)
· Use a drive of higher rating
3. Check the motor capacity
· Make sure the motor capacity is right
for the drive rating.
4. During a momentary power loss or
an attempt to reset a fault, the alarm is
displayed. However, there is no need
to take any action because the fault
display will disappear shortly
DNE
Driver Enable
1. Multi-function contact input
is set to 69/169, but the contact
input status is incorrect
2. The multi-function contact
input is incorrect
1. Multi-function contact input is set to
69 and switched on.
2. Multi-function contact input is set to
169 and switched off
AnL
Simulation A2 input signal is
lost
1. Simulation A2 input signal is
lost
1. Check the simulation signal wiring
2. Check the E3-10 parameter settings
ES
Emergency Stop
1. Emergency stop is turned on
(P2-11) before the power off,
when the DC bus voltage is
lower than P2-06
2. Multi-function contact input
is set to 21/121, but the contact
input is switched on
1. Turn off the emergency stop function
P2-11, or adjust P2-06 settings Level
2. Confirm the multi-function contact
input function set and terminal status
FBPL
(Water pump function)
Water shortage warning
1. The feedback pressure is
less than the water shortage
detection value (F1-09) and
1. Water shortage / water shortage
2. Judging that the level value is too
large
