If the rated capacity of the motor selected is not matching that of the CAN200 controller,
especially when the CAN200 controller’s rated power is greater than the motor’s, adjust
the motor protection parameters inside the controller or install a thermal relay to the motor
to protect the motor.
Running at over 50Hz
The CAN200 controller can output frequency of 0Hz-150Hz. If the user needs to make it
run at over 50Hz, please take the capacity of the machine.
Motor Heat and Noise
Since the output of CAN200 is PWM wave with certain harmonic wave, the motor
temperature, noise, and vibration will slightly rise compared with power frequency drive.
Voltage-sensitive Device or Capacitor at Output Side of the Controller
Because the CAN200 controller outputs PWM wave, the capacitor for improving power
factor or voltage-sensitive resistor for lightning protection shouldn’t be installed at the
controller’s output side. Otherwise, the controller may suffer transient over-current or even
be damaged.
Contactor at the I/O terminal of the Controller
When a contactor is installed between CAN200’s input terminal and the power supply, you
cannot start/stop the controller by turning the contactor ON/OFF. When a contactor is
installed between the controller output terminal and the motor, do not turn off the contactor
when the controller has outputs. Otherwise, modules inside CAN200 may be damaged.
When External Voltage is out of Rated Voltage Range
If external voltage is out of the allowable voltage range, the CAN200 controller
components may be damaged. If needed, please use corresponding voltage step-up or
step-down device.
Three-phase Input Changed into Two-phase Input
Do not change three-phase input of CAN200 into two-phase input. Otherwise, fault will
result or CAN200 will be damaged.
Lightning Strike Protection
A lightning strike protection device is installed inside the CAN200 controller. The user
should add lightning protection device to the front end of the controller in the places
subject to frequent lightning strikes.
Altitude and De-rating
In the places where the altitude is above 1000m and the cooling effect gets worse due to
rare air, it is necessary to de-rate the controller. Please feel free to contact our company
for detailed technical support.
