Attentions
Motor Insulation Inspection
Motor insulation inspection shall be performed before using a motor for the first time or
left unused for some time or during routine inspection, in order to avoid damaging
inverter due to failure of insulation performance of motor winding. Make sure to
disconnect motor cable from inverter during inspection; 500V megohmmeter is
recommended. The obtained insulation resistance from test shall not be lower than 5MΩ.
Motor Thermal Protection
If the selected motor does not match with inverter in rated capacity, especially when its
rated power is lower than that of inverter, be sure to adjust motor protection parameters of
inverter or install a thermal relay in front of the motor to protect the motor.
Operation at Power frequency
Output frequency of inverter ranges from 0.00 Hz to 600.00 Hz. To use inverter at over
50.00 Hz, please consider the bearing capacity of mechanical device.
Motor Heat and Noise
Since output voltage of inverter presents a PWM waveform along with some harmonic
waves, the temperature rise, noise and vibration of motor would increase a little in
comparison with the running under power frequency.
Varistor or Power Factor Improvement Capacitor on Inverter Output
Inverter outputs PWM wave. Do not use inverter, if a power factor improvement
capacitor or a lightning varistor is on output side, which may easily result in transient
overcurrent of inverter, or even damage inverter.
Beyond Rated Voltage
Do not use EM500 inverter outside the operating voltage range specified in this manual,
which may easily damage its internal parts. If you have to do so, install a voltage rise or
reduction device for transformation.

Surge Protection
A surge protection device is installed in inverter to prevent it from induction lightning
stroke on a certain degree. Additional protection devices are required in front of inverter
in the places where thunder and lightning occur frequently.
Altitude and Derating
When inverter is used in an area at an altitude of over 1,000m, the cooling effect will
degrade, so it must be derated. For details, please consult SINEE.
Attentions at Inverter Scrapping
Burning the electrolytic capacitors of the mains and PCB may result in explosion and
burning plastic parts may generate toxic gas. Please handle them as industrial wastes
when inverter is scrapped.

1.2.1Operating Status of Inverter
EM500 inverter operating status: Parameter setting status, normal running status,
JOG running status, autotuning status, stop status, JOG stop status and fault status.
Parameter setting status: After it is powered on and initialized and is standby
without a fault or a start-up command, inverter has no output.
Normal running status: Having received an active start command through
keypad, control terminal or communication, inverter drives motor as per the
setting input.
JOG running status: Drives motor at JOG input speed through setting of keypad,
external terminal or communication.
Autotuning status: Set through keypad to autotune the parameters of motor in
stationary or rotational autotuning.
Stop status: When a running command is inactive, output frequency drops to zero
as per set deceleration time.
JOG stop status: When JOG running command is inactive, output frequency
drops to zero as per JOG deceleration time.
Fault status: Status of inverter under protection, and all kinds of faults and
failures.

1.2.2Control Modes of Inverter
Control modes of inverter refer to what kind of method is adopted to drive motor at
desired speed or torque. These modes include:
VVF (Vector decoupling based VF control): The steady performance is the same as
that in SVC. Suitable for occasions of low speed change and low speed stability
accuracy and meet the needs of most AC motor drives.
SVC (Sensorless Vector Control): Advanced speed estimate algorithm, no need for
encoder, open loop vector control and high control accuracy.
1.2.3Setting Modes of Inverter
Setting mode of inverter refers to what kind of physical quantity is taken as the
control object when inverter drives motor.
Speed setting mode: Motor speed is taken as the control object;
This mode can be realized by numeric setting, analog input setting, high-speed pulse
input setting, communication setting, digital potentiometer setting, process PID, simple
PLC or preset speed, individually or jointly. In Figure 1-1 to Figure 1-4, various input
modes under the speed setting mode of EM500 are described:
Figure 1-1 Speed Input Mode
As indicated in Figure 1-1, there are mainly three speed setting modes of EM500,
respectively main frequency source A setting (referred to as “Main A” for short),
auxiliary frequency source B setting (referred to as “Auxiliary B” for short) and main &
auxiliary arithmetic setting. The speed setting mode is finalized by simple regulation and

Figure 1-2 Main Frequency Source A Setting
As indicated in Figure 1-2, when setting main frequency source A, user needs to
consider settings and status of numeric terminals comprehensively. According to terminal
settings, inverter can run at a preset speed or at a speed determined through numeric
setting, analog input, pulse or communication.
If all the numeric terminals are disabled, function code F00.04 is used to set present
channel and is in arithmetic together with UP/DOWN to get the final setting.

As indicated in Figure 1-3, when auxiliary frequency source B is being set, the
setting of F00.05 will be based upon to determine present setting channel. Process PID
and Simple PLC can participate in the setting.
Figure 1-4 Main and Auxiliary Arithmetic Setting
As indicated in Figure 1-4, main and auxiliary arithmetic can be classified into four
categories. At this time, both main and auxiliary settings are enabled.
Torque setting mode: Motor current is taken as the control object.
Torque setting mode can be set by multiple ways, which include numeric setting,
analog input setting, high-speed pulse input setting, communication setting, digital
potentiometer setting and preset torque setting. In Figure 1-5, various input modes for
torque setting of EM500 are described.
