01AC70-C Machine Tool Industry Purpose Variable Frequency Drive
Deceleration overexcitation function
If deceleration overexcitation is off, output current is small and deceleration time is long.
-01-
AC70-C is the latest development of a high performance machine tool purpose vector variable frequency drive. It
adopts leading magnetic flux algorithm and modular design to achieve high-performance and high-precision
motor drive control. Combining with the features of machine tool industry, the drive reliability has been enhanced
to meet the processing demands of different products.
Machine tool spindle adopts special macro parameter, which can simplify parameter setting.
With low frequency large torque output, torque dynamic response is fast.
With carrier smooth function, motor noise has been reduced effectively.
It is easy for the drive to deal with all kinds of severe environment with sealed design and thickened three anti-
paint treatment.

According to the set deceleration overexcitation current, the output current can be kept constant, which not only
can quickly consume motor feedback energy to prevent over voltage of bus capacitor but also can produce large
resistance torque to stop motor quickly and improve processing efficiency.
If deceleration overexcitation is on, output current increases and deceleration time shortens.

Compared with high-pitched motor noise of fixed carrier, output voltage harmonic spectrum of random carrier is
evenly distributed in a wide frequency range, which can reduce motor noise effectively.
Random carrier is on.
In low frequency and weak magnetic field, torque
performance is optimized.
It has linear torque feature in the whole speed
range.
Torque dynamic response time is less than 20ms.

Avoid frequent drive fault report to ensure its fast
response characteristics.

◎ PCB three anti-paint treatment: according to different
circuit board, the three anti-paint automatic spraying
equipment can design different spraying strategies,
and it can ensure three anti-paint coating thickness
uniformity and batch consistency.
With sealed design, it has good protection capability
in serve environment such as high resistance to
humidity, dust and vibration.
