■
Battery/UPS operation valid command “BATRY/UPS” (Function code data = 59)
The Battery/UPS operation can drive the motor during undervoltage situation. This can realize rescue operation
which rescues the passengers from the cage stopped halfway due to power failure in the lift application.
FRENIC-Ace has two types of operation and those are selectively used depending on the inverter capacity.
When “BATRY/UPS” is assigned to the digital input terminal, the operation becomes same as F14 = 0 regardless
of F14 setting, and the inverter trips immediately .
When “BATRY/UPS” is on, the input open phase protection operation becomes invalid regardless of the function
code H98 bit 1 setting.
Battery/UPS operation is divided into battery operation and UPS operation. Battery operation assumes that
operation is performed by supplying the main power from the battery, and control power from the UPS. Please note
that depending on the inverter capacity, battery operation and UPS operation may not be possible for certain
models.
(1) Connect the battery power supply before or simultaneously with turning on the BATRY/UPS signal.
(2) Between the period from turning on of the BATRY/UPS signal and MC2 (and power supply start
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/UPS
signal when the voltage is same or higher than the specified
undervoltage level (before lu is indicated after the power failure). If the
BATRY/UPS
signal is
turned on with the voltage same or higher than the undervoltage value, the specified level, 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 motor at 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/UPS
signal. If the main power is
turned on with the BATRY/UPS signal on, the 73X remains ON, causing the rectifier diode getting
damaged.
