About Motor and Load
Compared to Industrial Frequency Operation
The HD3N-L series controllers are voltage-type frequency controllers and their output is PWM wave
with certain harmonic wave. Therefore, the temperature, noise and vibration of the motor will be a
little higher than that at industrial frequency running.
Thermal Protection of Motor
When choose the adaptive motor, HD3N-L can effectively implement thermal protection of motor.
Otherwise it must adjust the motor protection parameters or other protection measures to ensure that
the motor is at a safe and reliable running.
Lubrication of Mechanical Devices
At long time low-speed running, provide periodical lubrication maintenance for the mechanical
devices such as gear box and geared motor etc. to make sure the drive results meet the site need.
Start and Stop HD3N-L
User should use the control terminal to start and stop HD3N-L. It is strictly forbidden to use contactor
or other switches on the input side of HD3N-L to start and stop directly, or it will damage the device.
Check the Insulation of the Motor
For the first time using the motor or after long time storage, it needs checking the insulation of the
motor. Worse insulation can cause damage to HD3N-L.
Note:
Use a 500V Mega-Ohm-Meter to test and the insulation resistance must be higher than 5M ohm.
