Functions
Motor Gear Ratio Setting Function
This function is useful for a system with an optional encoder installed on the machine side.
Set the number of actual encoder pulses in encoder pulses P011.
Set a motor-to-encoder rpm ratio in motor gear ratio numerator/denominator P028/P029.
With the above settings, the number of encoder pulses converted into motor shaft data is set in the
Inverter.
This function performs speed/position detection based on the number of encoder pulses converted
into motor shaft data and calculates the orientation stop position based on the number of encoder
pulses (P011).
Note: Make sure that the N/D setting is within the range of 1/50
≤
N/D
≤
20.
(N: Motor gear ratio numerator, D: Motor gear ratio denominator)
<Example>
• When the motor-to-encoder rpm ratio is 1:10, set the following data:
Number of encoder pulses (P011)
: 1024
Motor gear ratio numerator (P028)
: 10
Motor gear ratio denominator (P029)
: 100
In this case, the orientation stop position is defined as 4096 divisions of the encoder's one rotation.
Note that the concept of the stop position is inverted from the description in "Orientation stop
position conceptual drawing" (page 4-130).
Position Bias Function
Set this function to apply position command bias in the pulse train position control mode.
The set number of pulses is added to a change value at 2-ms internals. This is used for adjusting
the phase of synchronization points during synchronous operation.
Set an addition value in position bias amount P024. A positive value adds the value in the forward
direction.
