Description Check point and remedy reference
Re-calculate the relationship between brak-
ing load calculations and braking capacity.
→ Reduce braking load.
→ Review braking resistor selection, and
increase braking capacity.
(Resetting of objects 3004Hex-33Hex,
3004Hex-34Hex, 3004Hex-35Hex data
is necessary)
Recalculate deceleration torque and deceler-
ation time required from the moment of iner-
tia of the load and deceleration time.
→ Lengthen deceleration time (parameters
3004Hex-09Hex, 3005Hex-0CHex,
3005Hex-0EHex, 3005Hex-10Hex,
3008Hex-39Hex)
→ Review braking resistor selection, and
increase braking capacity.

is necessary)
•
Check that the output from the safety
switch is input using the same logic (High
or Low/Low) to both terminals [SF1]/[SF2].
→ Cycle the power to clear the alarm.
If this is not resolved by the procedure
above, the inverter is faulty.
→ Replace the inverter.
