Preface
The -S3 Series of elevator-used Inverters is a new type inverter which is
researched and developed based on the carry characteristic of elevator. The 32
bit electromotor-used Digital Signal Processing (DSP), Complex Programmable
Logic Device (CPLD), Intelligent Power Module (IPM) and the digiral vector
controlled frequency-variable speed-adjustable technology are used in the
Inverter. It also combines the model characteristic of potential energy. All of them
ensure stable, comfortable and efficient running of elevator.
Outline
This instruction manual describes installation, operation, function constants
setting, maintenance and trouble-shooting of the -S3 Inverter. The
manual can be the reference for designing the elevator control system by using
the -S3 Inverter. It also can be the reference of installation,
commissioning and maintenance of elevator.
Please read the manual carefully before installing and operating the inverter.

Innovations
a) The innovative starting compensation technique without load sensors
provides an excellently comfortable starting of elevator.
b) The new PWM dead-zone compensation technique can effectively reduce
motor noise and wearing.
c) There is no need to run autotuning for asynchronous motor.
d) There is no need to lift the car during self-tuning of the phase angle of
elevator with synchronous motor.

Instruction Manual of -S3 Inverter for Elevator
Convenient and quick commissioning method of elevator
It is important whether it is convenient for elevator commissioning after wiring.
Usually it takes operators much time and effort to set many parameters and
perform complicated procedures. This becomes very convenient by using our
inverter which is designed especially for elevator. There are only three steps for
commissioning:
1 Adjusting running direction
The correct encoder wiring and motor running direction can be easily identified
by the operator.
2 Setting parameters
a) Users may use the leave-factory configuration of motor parameters directly
identified and/or set by us, or
b) Enter the motor parameters into the inverter according to the motor
nameplate.
3 Adjusting feeling
a) The comfortable feeling may be obtained by the leave-factory values of the
parameters.
b) This may be further improved through minor adjustments of C parameters
of PID.

1.6 Handling notice
When using the -S3 Inverter, please pay attention to the following:
1.6.1 Choice of Braking Resistor
The elevator control system is running in four quadrants with potential load and negative
torques. Therefore, the choice of braking components shall be considered in order to avoid
over-current and overvoltage trip. The -S3 Inverter has built-in braking unit and only
needs an external braking resistor. Table 1.1 shows the braking resistor specifications for
200V Inverters and Table 1.2 for 400V.

1.6.2 Absorbing device is prohibited on the output side
Since the output of the Inverter is impulse, trip or damage to devices may occur if capacitors
for improving power factor or varistors for lightening protection are installed on the output
side. This shall be considered during design. The capacitors and varistors wired to the
existing output side of the circuit shall be removed during modernization of old elevators.
Never wire the capacitor on the output side of the Inverter circuit. This is sketched in Figure
1.3.

1.6.3 Operation Voltage of Inverter
The operation voltage of the -S3 Inverter shall be at its nominal level, i.e.,
220V/380V. If the power supply does not provide the appropriate voltage, a transformer
must be used.
1.6.4 2-phase power supply is prohibited
3-phase power supply may not be changed to 2-phase, or faults may occur.
1.6.5 User control of output contactor
If the output contactor is not controlled by the -S3 Inverter but by the user program,
it is recommended to pull in the contactor before sending the running command to the
Inverter and to pull it off a while after the signal output of the elevator has been stopped in
order to ensure correct operation of the contactor without current.

1.6.6 Altitude and derating operation
In areas with an altitude above 1000m, thin air will lower the heat dissipation capacity of the
Inverter, and thus the Inverter shall be operated at a derated level. Figure 1.4 shows the
relationship between nominal output current and altitude.

1.7 Discarding Notices
The discarded Inverter shall be disposed as industrial garbage.
1.7.1 Capacitor Disposal
Explosion may occur during burning of the chemical capacitor on the main circuit or PCB.
Therefore, burning chemical capacitor is prohibited.
1.7.2 Plastic Parts Disposal
There are many plastic parts on the Inverter, the burning of which will generate poisonous
