Func
tions
Momentary Power Interruption Non-stop Deceleration Stop (b050 = 01)
• After the power is shut off during operation, this function decelerates the Inverter to a stop while
keeping the voltage below the momentary power interruption non-stop deceleration level (b052).
• To use this function, remove the J51 connector cable connected between terminals Ro and To,
and connect the cable from main terminal P to Ro, and from N to To. The cable size should be 0.75
mm
2
or larger.
• If the power is shut off during operation and the voltage falls below the momentary power
interruption non-stop function starting voltage (b051), the frequency deceleration width decreases
at the momentary power interruption non-stop deceleration starting width (b054), and then the
Inverter decelerates for the momentary power interruption non-stop deceleration time (b053).
• If an overvoltage condition (momentary power interruption non-stop deceleration level b052 or
higher) occurs because of regeneration during deceleration, the Inverter is kept in the LAD STOP
status until the overvoltage condition is reset.
*1. When the momentary power interruption non-stop deceleration level (b052) < the momentary
power interruption non-stop function starting voltage (b051), the Inverter performs this function
by increasing the momentary power interruption non-stop deceleration level (b052) to the
momentary power interruption non-stop function starting voltage (b051). (The set value will not
be changed.)
If b052 is lower than the incoming voltage or equivalent (DC voltage or equivalent after
rectification [incoming voltage ×
√⎯
2]), the Inverter is brought into the LAD STOP status at power
recovery during execution of this function, disabling deceleration. (The Inverter will accept
neither a STOP command nor frequency reference change until operation is complete.) Make
sure that the b052 setting is higer than the normal incoming voltage or equivalent.
*2. This function is not reset before the operation is complete and stopped. To run the Inverter after
power recovery during this function, input the RUN command following the STOP command
(RUN command OFF) after a stop condition.
*3. If the momentary power interruption non-stop deceleration starting width (b054) is too large, an
overcurrent trip occurs because of rapid deceleration. If b054 is too small, or if the momentary
power interruption non-stop deceleration time (b053) is too long, an undervoltage trip occurs
because of insufficient regeneration power.
