Wait For Interlock Timeout
The digital input set to Run Interlock is open.
•
Install a NC BAS Interlock Circuit/Damper Interlock between
DI-x and IG-24 on PCB A2.
•
Install a jumper between DI-2 and IG-24 on PCB A2. Use this
method when you will add a a safety circuit in the future or if
you will not use a safety circuit.
•
Make sure that the input assigned for the Interlock is active in the
timeout period set in
Z1-15
.
Note:
Do a Fault Reset to clear the fault.

activated.
Remove the cause of the external fault.
An external fault (EFB) was received from the serial
communications network.
•
Remove the cause of the external fault.
•

Motor Overload
The load is too heavy.
Decrease the load.
The cycle times for acceleration and deceleration are
too short.
Increase the acceleration and deceleration times in
C1-01
and
C1-
02
.
You are driving a general-purpose motor below the
rated speed with a high load.
•
Decrease the load
•
Increase the speed
•
If the motor is designed to operate at low speeds, increase the
motor capacity or use a motor designed to operate in the desired
speed range.
The motor current in
E2-01
is incorrect.
•
Check the motor rated current.
•
Enter the motor rated current as shown on the motor nameplate
to
E2-01
.
The maximum output frequency in
E1-03
is incorrect.
Check the
E1-03
setting and correct it.
You are operating more than one motor from one
bypass.
Set
L1-01 = 0
to disable motor protection and install a thermal relay
to each motor.
The electrical thermal protection characteristics and
the motor overload characteristics do not align.
•
Make sure that the motor characteristics are correct for the
application.
•
Set
L1-01
to the correct type of motor protection.
•
Install an external thermal relay.
The electrical thermal relay is operating at an
incorrect level.
•
Check the current rating as shown on the motor nameplate.
•
Check the
E2-01
value.
Note:
Do a Fault Reset to clear the fault.
