(Supplement to Instruction Manual)
High Performance, Multifunction Inverter
About this document
This manual, a supplement for the FRENIC-MEGA series of inverters having a ROM version 3600 or later, contains addition,
modification, and correction to the FRENIC-MEGA Instruction Manuals (INR-SI47-1183b-E, INR-SI47-1223c-E,
INR-SI47-1334-E, and INR-SI47-1335a-E). For other descriptions, refer to the original manuals.
Checking the inverter's ROM version
The inverter's ROM version can be checked on Menu #5 "Maintenance Information" ( 5 _ 14 ) as a 4-digit code. For the
detailed keypad operation, refer to the inverter original manuals.
About newly added functions
The functions listed below are newly added to the FRENIC-MEGA series of inverters having a ROM version 3600 or later.
For details about those functions, refer to Section 2 "Details of Function Codes Added" or the PG Interface Card Instruction
Manual.
Inverter's ROM Version Newly Added Functions
3600 or later (1) Online tuning
Performs tuning while the motor is rotating in order to cover the motor speed
fluctuation caused by the temperature rise of the motor.
(2) Function extension of brake signal
Extends the brake-ON sequence function.
(3) PG error processing
Changes the PG error detection width if the speed command exceeds the base
frequency.
(4) Synchronous operation
Enables synchronous operation of two motors equipped with a pulse generator
(PG). The PG interface card (OPC-G1-PG or OPC-G1-PG22) is required. For
details, refer to the PG Interface Card Instruction Manual.
(5) Motor magnetic flux weakening control under "vector control without speed
sensor"
Improves the torque control stability. The overspeed detection level can be
specified.
(6) Improved regenerative power control under vector control
Adjusts the motor magnetic flux level to be applied during deceleration under
vector control.
(7) Terminal command "Enable battery operation" BATRY
(Function code data = 59)
Cancels the undervoltage protection so that the inverter under an undervoltage
condition runs the motor with battery power.
(8) "0 to 20 mA" range added to analog input/output
(9) Speed limit level adjustable with analog inputs under torque control
The PG interface card OPC-G1-PG22 is applicable to inverters having a ROM version 3510 or later.

59 1059 Enable battery operation BATRY YYY Y Y
■Enable battery operation -- BATRY (Function code data = 59)
Turning this terminal command ON cancels the undervoltage protection so that the inverter runs the motor with battery
power under an undervoltage condition.
When BATRY is assigned to any digital input terminal, the inverter trips after recovery from power failure just as F14 =
1 regardless of F14 setting. When BATRY is ON, the main power down detection is disabled regardless of H72 setting.

Prerequisites for battery operation
(1) The terminal command BATRY (data = 59) must be assigned to any digital input terminal.
(2) A DC link bus voltage must be supplied from the battery to the main circuit (L1/R-L3/T or L2/S-L3/T) as
shown in Figures A and B given below.
(3) A regulated voltage (sine-wave or DC voltage) must be supplied to the auxiliary power supply (R0-T0).
(4) For 200 V class series of 37 kW or above and 400 V ones of 75 kW or above, a regulated voltage
(sine-wave) must be supplied to the auxiliary fan power supply (R1-T1) as shown in Figure B. The fa
n
power supply connector must be configured for battery operation as shown in Figure C.
(5) The BATRY-assigned terminal (data = 59) must be turned ON at the same moment as closing of MC2.

About battery operation (when BATRY is ON)
(1) The undervoltage protective function (
lu ) is deactivated.
(2) The inverter can run the motor even under an undervoltage condition.
(3) The RDY ("Inverter ready to run") output signal is forcedly turned OFF.
(4) The bypass circuit of the charging resistor comes to be closed (73X ON) after a delay of time T1 fro
m
when the BATRY is turned ON. Further, after a delay of time T2 (a maximum of 0.1 second), the battery
operation starts. For the specifications of T1, see the table below.

k: Safety coefficient (Less than 1, about 0.8)
Precautions
(1) The battery power supply must be connected before or at the same moment as turning ON of BATRY.
(2) As shown in the timing diagram above, battery operation is possible within the battery operation-enable
d
zone. There is a delay of "T1 + T2" after the BATRY, MC2, and battery power supply are turned ON.
(3) The BATRY must not be turned ON when the voltage level is higher than the specified undervoltage level
(that is, before the lu appears after a power failure). Turning the BATRY ON causes the bypass circui
t
(73X) of the charging resistor to stick to ON (closed).
(4) During battery operation, driving with a heavy load must be avoided and the motor must run with no loa
d
or braking load condition. Low battery voltage cannot generate sufficient torque, causing the motor to
stall.
(5) The battery operation must be performed at a low speed. Be careful with the battery capacity.
When a high voltage (e.g., 300 VDC for 200 V class series of inverters or 600 VDC for 400 V ones) is
applied, not battery operation but normal operation must be performed.
(6) In normal operation, the BATRY must be OFF. Turning the main power supply ON with the BATRY bein
g
ON could damage the rectifier diode because the 73X is ON.

Motor 1/2/3/4 (Online tuning)
Long run under "Dynamic torque vector control" or "Slip compensation control" causes motor temperature change,
varying the motor parameters. This changes the motor speed compensation amount, resulting in motor speed deviation
from the initial rotating speed.
Enabling online tuning identifies motor parameters covering the motor temperature change to decrease the motor speed
fluctuation.
To perform online tuning enabled with P05/A19/b19/r19, set P04 (Auto-tuning) to "2."
Note: Online tuning can be performed only when F42 = 1 (Dynamic torque vector control) or when F42 = 2
(V/f control with slip compensation active) and F37 = 2 or 5 (Auto torque boost).

Brake Signal
These function codes are for the brake releasing/turning-on signals of vertical carrier machines.
It is possible to set the conditions of the brake releasing/turning-on signals (current, frequency or torque) so that a
hoisted load does not fall down at the start or stop of the operation, or so that the load applied to the brake is reduced.
Releasing the Brake
When any of the inverter output current, output frequency, or torque command value exceeds the specified level of the
brake signal (J68/J69/J95) for the period specified by J70 (Brake signal (Brake-OFF timer)), the inverter judges that
required motor torque is generated and turns the signal BRKS ON for releasing the brake.
This prevents a hoisted load from falling down due to an insufficient torque when the brake is released.

J68 Brake-OFF current 0% to 300%:
J69 Brake-OFF frequency/speed 0.0 to 25.0 Hz Available only under V/f control.

J95 Brake-OFF torque 0% to 300% Available only under vector control.
J96 Speed condition selection
(Braking conditions)
Response for brake-OFF current (Bit 2)
0: Slow response (default)
1: Quick response
Specifies the response type for
brake-OFF current detection.
Selecting slow response inserts a
detection filter into the current detection
circuit so that the brake-OFF timing will
be slightly behind the rising edge of the
actual current.
If the delay is not negligible with
adjustments, select quick response.
Turning the Brake ON
When the run command is OFF and the output frequency drops below the level specified by J71 (Brake signal
(Brake-ON frequency/speed)) and stays below the level for the period specified by J72 (Brake signal (Brake-ON timer)),
the inverter judges that the motor rotation is below a certain level and turns the signal BRKS OFF for activating the
brake.

10
Under vector control, when the reference speed or the detected one drops below the level of the brake-ON frequency
(specified by bit 3 of J96) and stays below the level for the period specified by J72 (Brake signal (Brake-ON timer)), the
inverter judges that the motor rotation is below a certain level and turns the signal BRKS OFF for activating the brake.
This operation reduces the load applied to the brake, extending lifetime of the brake.

used for brake-ON timing.
If "Detected speed" and "Stop frequency"
are selected (Bit 0 = 0 and Bit 3 = 0) to
determine brake-ON timing, the brake
may be applied after running at the stop
frequency (F25) due to a speed error.
If it is required that brake is applied
during running at the stop frequency,
select "Brake-ON frequency" (Bit 3 = 1)
as criteria of frequency.
When jogging or inching the motor for
vertical conveyance, use J71 as
brake-ON frequency.
Turn-on condition of brake signal (Bit 4)
0: Independent of a run command
ON/OFF
1: Only when a run command is OFF
(Available only under vector control.)
Specifies whether to turn on a brake
signal independent of a run command
ON/OFF or only when a run command is
OFF.
When normal and reverse operations are
switched, brake-ON conditions may be
met in the vicinity of zero speed. For
such a case, select "Only when a run
command is OFF" (Bit 4 = 1).
