NE200/300 Series Drive User Manual
Chapter 6 Parameter description 173
needs to set the corresponding input terminal to length count input terminal.
And input terminal X4 or X5 is usually used when the pulse frequency is
relatively high.
Actual length = counted terminal input pulse number ÷ number of pulse
per unit.
When the actual length FB.01exceeds the preset length FB.00, the
multifunction digital output terminal defined as “length arrival terminal” will
output ON signal.
6.13 Protection and fault parameters group (FC)
FC.00 Motor overload protection
mode
Range: 0～2【0】
0: Disabled
The overload protection is disabled. Be cautious to use this function
because the drive will not protect the motor in case of overload.
1: Common motor (with low speed compensation)
Since the cooling effects of common motor deteriorates at low speed
(below 30 Hz), the motor’s overheat protecting threshold should be
lowered, which is called low speed compensation。
2: Variable frequency motor (without low speed compensation)
The cooling effects of variable frequency motor are not affected by the
motor’s speed, so low speed compensation is not necessary.
FC.01 Electro thermal protective
value
Range: 20～110%【100%】
In order to apply effective overload protection to different kinds of motors,
the Max output current of the drive should be adjusted, as shown in
Fig.6-27.
