2 Chapter 1 Safety Rules
The standard TD3200 drive has no operation keypad and display unit. You
may choose them based on your needs.
2. Low Speed Running with Constant Torque
Driving a common motor at low speed for a long time, the motor's life will be
reduced due to the deteriorating heat dissipation effect, so a special variable
speed motor for this case.
3. Insulation of Motors
Before using the drive, please check the insulation ratings of the motors to
avoid damage. When the environmental conditions are unfavorable to the
motor, please check the insulation conditions at a regular interval to ensure
the safety of the whole system.
4. Regenerating load
For the load to be elevated, it may bring regenerating torque. The drive will
trip due to over-current and over-voltage. If the drive needs to drive such load,
you should select brake resistor.
5. Do Not Install Varistors or Capacitors at Output
You must remove the capacitors or voltage sensitive devices installed at the
output for improving power factor, because they will result in drive trip or
other devices damaged. Besides, you'd better not install air-break switch or
contactor. If you have to do so, you must ensure that when the switches act,
the output current of the drive is zero. Please refer to Figure1-1.

6. Derating at Base Frequency
When the base frequency is set below the rated frequency, derate the drive to
prevent the motor from being damaged due to overheat.
