1. General Description

1.1 Functionality

Please be sure to take into account all applicable standards and regulations before applying the

SJ300EL inverter to an elevator system.

1.2 Instruction manual

This supplementary manual for the SJ300EL Elevator AC Inverter is to be used in conjunction with the

SJ300 general purpose inverter manual. Information shown in this manual takes precedence over the

manuals of the SJ300 inverter (and the SJ-FB option card manual, if used), where there are differences.

1.3 Functionality

Differences of functions versus the general purpose SJ300 inverter are shown in the following table. The

settings can be viewed or modified by the standard digital operator or the optional copy unit (SRW-0EX).

Multi-language display however is not supported with the SJ300EL and the SRW-0EX.

1.4 Added and modified functions vs. standard SJ300

# Function name Contents Remark

1 Characteristics of

S-curve acceleration &

deceleration for elevators

Characteristics of each curve portion and linear portion

can be adjusted separately.

2 Acceleration/

deceleration time setting

of multi-stage speed

Acceleration/deceleration time can be set for each

multistage speed (0-7) independently.

3 Gain adjustment

(P-gain, I-gain) P-gain and I-gain can be adjusted for each of up to 8

(eight) preset frequencies.

4 Torque bias gain

adjustment Torque bias setting input can be given via voltage input

or torque bias input.

5 Battery backup function Emergency drive (low speed) can be done by an

external battery in case of main power failure. Note1

6 Control mode

changeover in case of emergency Changes the control mode to V/Hz (V/f) or SLV in case

vector control cannot function due to an encoder failure.

7 Brake control function Brake ON frequency and brake OFF frequency can be

set separately. Brake

ON and OFF wait time can be set

Separately. Additionally, delay time at brake OFF can be

set. Delay time can be set at brake OFF.

8 Encoder Errors If the signal from the encoder doesn’t correspond to the

inverter output for any reason, then the inverter displays

a trip event.

Note 1) Please contact Hitachi with the following information if the battery back-up function is needed.

(Note 1) A linear characteristic will result (A097 = A098=00) if 0% is set for the curve ratio.

(Note 2) A linear characteristic will result if the change of the target speed is less than or equal

to 10% of the maximum frequency.

(Note 3) All of the curve constants are ignored if “04” is selected in A097 and A098. Refer to the

manual for standard S-curve acceleration & deceleration description.

(Note 4) The S-curve will be recalculated if the target speed is changed while accelerating or

decelerating. Therefore do not use analog signals for the target speed.

(Note 5) Curve ratio for acceleration/deceleration must be in the range of 10% up to 50%.

Chapter 2 – Explanation of Functions

2.2 Multi-speed and acceleration/deceleration time

Different acceleration and deceleration times can be set for each multistage speed. The acceleration

time is the one used between the current speed and target speed during acceleration. The deceleration

time is the one used between the current speed and creep speed (speed-7), or between the current

speed and the target speed during deceleration. Therefore use the deceleration time of A027 for creep

speed at stopping. Furthermore, inverter decelerates with the deceleration time that is set on that

multistage speed when the RUN command is removed.

Related parameters are shown in following table.
