5.3 Description of Function Codes 5.3.2 E codes (Extension terminal functions)
Home position limit switch “LS” assignment (Function code data = 42)
This is a home position limit switch signal used for position control.
Refer to function codes d201 to d299 for details on position control.
Enable overload stop “OLS” assignment (Function code data = 46)
Turning this terminal command ON enables the overload stop function; turning it OFF disables the function. If no
OLS is assigned, the function is enabled.
( Function codes J63 to J67)
Servo-lock command “LOCK” assignment (Function code data = 47)
Turning this terminal command ON enables a servo-lock command; turning it OFF disables a servo-lock command.
( Function codes J97 to J99)
Pulse train input “PIN”, Pulse train sign “SIGN” assignment (Function code data = 48, 49)
Frequency setting by pulse train input is possible with terminal [X6] and [X7]. It is necessary to assign terminal [X6]
and [X7] to pulse train input [PIN]. Assigning the command “SIGN” to one of the digital input terminals except [X6]
and [X7] enables the pulse train sign input to specify the polarity of frequency command.
( Function code F01)
UP/DOWN frequency clear “STZ” assignment (Function code data = 58)
If save initial value with frequency setting is selected (H61 = 1) with the UP/DOWN signal, the initial value is forcibly
cleared to zero when this signal is turned ON.
( Function code F01)
Battery operation valid command “BATRY” assignment (Function code data = 59)
The Battery 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. When “BATRY”
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” is on, the input open phase protection operation becomes invalid regardless of the function code
H98 bit 1 setting. Furthermore, main circuit power cutoff is also disabled regardless of the H72 function.
Battery operation is possible with FRN0008G2S-2G to FRN0180G2S-2G and FRN0004G2□-4G to FRN0150G2□
-4G, and assumes that operation is performed by supplying the main power from the battery, and the control power
as sine wave voltage or DC voltage from the auxiliary power terminals (R0 to T0).
(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 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” signal when the voltage is same or higher than the specified
undervoltage level (before lV 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 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 200V series
inverter and 600 VDC power supply at 400V series 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.
