Chapter 5 Function Code
Table 5.4-73 Time from BATRY ON to 73X ON: T1
Power supply condition 30 kW or below 37 kW or above
Time required for turning on the control power
supply, switching to the power supply from the
battery, and then to turning on the charging
resistor short circuit 73X
100 ms 500 ms
Time required from the occurrence of
momentary power failure in the control power
supply ON status, switching to the power
supply from the battery, and turning on of the
short circuit 73X for the charging resistor
205 ms
(5) S-curve acceleration/deceleration becomes invalid.
(6) The operable speed during the battery operation is calculated by using the following
expression.
Battery voltage - 5 [V]
Frequency command during
rescue operation in powe
failure ≤
2 × Base voltage (F05)
x Base frequency (F04) x k
Here,
Battery voltage: 24 VDC or higher (200 V class)
48 VDC or higher (400 V class)
Rated frequency: F04
Rated voltage: F05 (Motor rated voltage (V))
k: Safety factor (Lower than 1 Approx. 0.8)
Note
(1) Connect the battery power supply before or simultaneously with turning on the BATRY signal.
(2) Between the period from turning on of the BATRY signal and MC2 (and power supply star
from the battery) to the state that the battery operation is possible, the delay time "T1" + "T2"
indicated in the above "time chart" occurs.
(3) Do not turn on the BATRY signal when the voltage is same or higher than the specified
undervoltage (before
lu
is indicated after the power failure). If the BATRY signal is turned on
with the voltage same or higher than the undervoltage value, the specified amount, the short
circuit for charging resistor 73X remains on.
(4) During the battery operation, avoid driving with application of the heavy load. Operate with no
load or braking load.
(Sufficient torque cannot be obtained by the battery voltage, and the motor may stall in such
case.)
(5) Operate the battery in a low speed, and pay attention to the battery capacity.
In addition, when the high voltage is supplied (such as when 300 VDC power supply at 200 V
class inverter and 600 VDC power supply at 400 V class inverter), operate normally without
the battery.
(6) During the normal operation, it is required to turn off the BATRY signal. If the main power is
turned on with the BATRY signal on, the 73X remains ON, causing the rectifier diode getting
damaged.
