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.

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.

2.3 Multi-speed Gain adjustment
Unique ASR (automatic speed regulator) gains (P-gain and I-gain) can be assigned for each output
frequency. The gain of 100% is calculated based on a value of motor inertia (J: H024, H034), speed
response coefficient (H005) and parameters of H070, H071, and H072, adjustable from 0% up to 100%.
Set the frequencies so f1<f2<xxx<fn<xxx<f7<f8. There is no restriction for the setting of the gains.
Set gain of the maximum frequency (G8 in following figure) is maintained when a higher target frequency is
set.

(1) The purpose of this function is to get high gain at brake OFF and at stopping, and to have low gain
at higher speed. Therefore increase the gain at a speed that is lower than the creep speed as a
rough initial target.
(2) When using a geared motor decrease H005, H050, H051, H070, H071, and/or H072. Set H005 of
around 1.0-2.0 in the range of lower than the creep speed, as a rough target.

Note 2: When OI input is used for torque bias, the ranges of P110 and P111 are still 0 – 10 V, so it will be
necessary to translate the 4 – 20 mA signal value to 0 – 10 V for these parameter settings.

2.6 Control mode changeover in case of emergency
If the elevator cannot operate in vector mode with feedback mode (due to encoder failure, for
example), the control mode can be changed to V/f or SLV mode to allow short term emergency
operation. Changeover is initiated by an intelligent input configured to the [ECM] function.
NOTE: Do not use this mode as a normal operation mode.
