Interface
Nominal Bus Voltage (Vbus)
The Nominal Bus Voltage can be calculated by multiplying the Nominal AC mains
voltage supplied by 1.41. When using a model with the suffix “S1N” where the mains
are wired to the “Doubler” connection, the Nominal Bus Voltage will be doubled.
Example:
If the mains voltage is 230VAC, Vbus = 230 x 1.41 = 325V
This value is the initial voltage for the drive and the correct voltage will be calculated
dynamically depending on the drive’s incoming voltage value.
Rotor Moment of Inertia (Jm)
From motor manufacturer or nameplate.
NOTE
Round the calculated result to 3 significant places.
Maximum Motor Speed in RPM
This is also listed as “Speed @ Vt” (motor speed at the terminal voltage rating). The
maximum motor speed will typically be a round even value between 1000 and 6000
RPM.
Number of Poles
This is a positive integer number that represents the number of motor poles, normally
2, 4, 6 or 8.
4.6.3.2 For Motors Equipped with Incremental Encoders Only
Encoder Line Count
The Encoders for servomotors normally have Line Counts of 1000, 1024, 2000, 2048,
4000, or 4096. The Encoder Line Count must be a positive integer and must be pre-
quadrature.
Index pulse offset. Enter 0 (zero)
Index marker pulse position. This field is reserved for backward compatibility. All
PositionServo drives determine actual marker pulse position automatically.
