Chapter 7 Creating Custom Motors

Creating Custom Motor
Parameter Sets

Use the Motor Database command buttons to access Rotary or Linear motor
parameter windows. These windows configures, and then saves or deletes the
custom motor parameter set.

The requirements of a motor for use by an Ultra-Series drive include:

Motor must have a TTL level, incremental, quadrature encoder with
commutation signal, or

A sine/cosine encoder with commutation signals.

Motor inductance must be greater than 1 milliHenry.

Motor electrical time constant (phase-to-phase inductance divided by the
phase-to-phase resistance) must be greater than 1 ms.

From the main Motor Database window:

1. Use one of these commands:

Click a command button

New Rotary to create a custom rotary motor with default values.
New Linear to create a custom linear motor with default values.

Click a motor model from the list that approximates your custom
motor (Type, Speed, Current and Mass/Inertia parameters) and then
click the Duplicate toolbar, or double-click the motor.

2. Modify the Rotary or Linear motor parameters as required. See

Using the Linear Motor Window

, or

Using the Rotary Motor Window

for information on motor parameters that can be set.

3. Click the Close button to exit the New Rotary motor or New Linear

motor window.

The custom motor appears in the Motor Database window with the abbreviated
parameter set as created, modified or unaltered.

TIP

If no commutation signals are available, the Start Up Type
parameter must be set for Self-Sensing (resolvers are not
supported).

TIP

Set all Flux Saturation levels at 1.000 for any custom motor.
