3. Motor heat and noise
The output of the controller is pulse width modulation (PWM) wave with certain harmonic
wave, and therefore, the motor temperature rise, noise, and vibration are slightly greater
than those at running with the power frequency (50 Hz).
4. Voltage-sensitive device or capacitor on the output side of the controller
The controller outputs PWM waves, and therefore, do not install the capacitor for improving
power factor or lightning protection voltage-sensitive resistor on the output side of the
controller. Otherwise, the controller may suffer transient overcurrent or even be damaged.
5. Contactor on the input and output sides of the controller
When a contactor is installed between the input side of the controller and the power supply,
the controller must not be started or stopped by opening or closing the contactor. When a
contactor is installed between the output side of the controller and the motor, do not open or
close the contactor when the controller has output. Otherwise, modules inside the controller
may be damaged.
6. Use outside the rated voltage
The controller must not be used outside the allowable voltage range specified in this
manual. Otherwise, components inside the controller may be damaged. If required, use a
corresponding voltage step-up or step-down device.
7. Surge suppressor
The controller has a built-in voltage dependent resistor (VDR) for suppressing the surge
voltage generated when the inductive loads (electromagnetic contactor, electromagnetic
relay, solenoid valve, electromagnetic coil and electromagnetic brake) around the controller
are switched on or off. If the inductive loads generate very high surge voltage, use a surge
suppressor for the inductive load or also use a diode.
Note
Do not connect the surge suppressor on the output side of the controller.
8. Altitude and de-rating
In places where the altitude is above 1000 m and the cooling effect reduces due to thin air, it
is necessary to de-rate the controller. Contact Monarch for technical support.
9. Adaptable motor
The controller is adaptable to squirrel-cage asynchronous motor or AC PMSM. Select a
proper controller according to motor nameplate.
The default parameters configured inside the controller are squirrel-cage asynchronous
motor parameters. It is still necessary to perform motor auto-tuning or modify the default
values based on actual conditions. Otherwise, the running effect and protection performance
will be affected. For PMSM, motor auto-tuning must be performed.
10. Precautions on selecting residual-current circuit breaker (RCCB)
Tripping may be caused if an improper RCCB is selected when the controller drives the
motor. This is because the output wave of the controller has high harmonics and the motor
