Adjusting Calculated Motor Data
When configuring new motors, you may want to adjust
the calculated Motor Data (Figure 3-8) in the Amplifier
Status Now! screen. This section takes this scenario
into account.
Note: Calculated data is defined as motor data, which is
displayed in the Amplifier Status Now! screen. It was
previously preliminary motor data, which was entered
into the Motor Data >Specification screen and
calculated when the Calc Amp Data button was
selected.
The Current Limit Source can be external or internal.
When set to External, a voltage or resistance is used to
set the peak current limit. When Internal, the continuous
current limit and peak current limit values are used.
The average voltage can be limited to the motor by
setting the PWM Limit % .
Phase Counts , or the number of encoder counts per
electrical cycle (pole pair), is an important value which
must be set accurately. The value may be determined
using this equation:
Phase Count = Counts per rev. / no. of pole pairs
In this example (Figure 3-8), 4000 counts per revolution
divided by 2 pole pairs equals 2000 phase counts .
Halls Present
Commutation Mode can be set to either Trapezoidal
or Sinusoidal If the motor has Hall sensors. The Phase
Mode can be set to either Hall-based or Algorithmic.
You should proceed to the next sections Encoder
Checking and Auto Phasing.
