(8) Compliance with SEMI-F47 standard
POINT
The control circuit power supply of the servo amplifier can be possible to comply
with SEMI-F47 standard. However, a back-up capacitor may be necessary for
instantaneous power failure in the main circuit power supply depending on the
power supply impedance and operating situation.
Use a 3-phase for the input power supply of the servo amplifier. Using a 1-phase
100 V AC/200 V AC for the input power supply will not comply with SEMI-F47
standard.
The external dynamic brake cannot be used for compliance with SEMI-F47
standard. Do not assign DB (Dynamic brake interlock) in [Pr. PD07] to [Pr.
PD09]. Failure to do so will cause the servo amplifier to become servo-off when
an instantaneous power failure occurs.
Be sure to perform actual machine tests and detail checks for power supply
instantaneous power failure of SEMI-F47 standard with your equipment.
The following explains the compliance with "SEMI-F47 semiconductor process equipment voltage sag
immunity test" of MR-J4 series.
This function enables to avoid triggering [AL. 10 Undervoltage] using the electrical energy charged in the
capacitor in case that an instantaneous power failure occurs during operation.

Set the time [ms] of the [AL. 10.1 Voltage drop in the control circuit power]
occurrence.
Enabling SEMI-F47 function will change operation as follows.
1) The voltage will drop in the control circuit power with "Rated voltage × 50% or less". 200 ms later,
[AL. 10.1 Voltage drop in the control circuit power] will occur.
2) [AL. 10.2 Voltage drop in the main circuit power] will occur when bus voltage is as follows.

Instantaneous maximum output means power which servo amplifier can output in maximum torque
at rated speed. You can examine margins to compare the values of following conditions and
instantaneous maximum output.
Even if driving at maximum torque with low speed in actual operation, the motor will not drive with
the maximum output. This can be handled as a margin.
The following shows the conditions of tolerance against instantaneous power failure.
1) Delta connection
For the 3-phase (L1/L2/L3) delta connection, an instantaneous power failure occurs in the voltage
between a pair of lines (e.g. between L1 and L2) among voltages between three pairs of lines
(between L1 and L2, L2 and L3, or L3 and L1).
2) Star connection
For the 3-phase (L1/L2/L3/neutral point N) star connection, an instantaneous power failure occurs
in the voltage between a pair of lines (e.g. between L1 and N) among voltages at six locations,
between three pairs of lines (between L1 and L2, L2 and L3, or L3 and L1) and between one of
the lines and the neutral point (between L1 and N, L2 and N, or L3 and N).
