Closed Loop Vector Control Operations
Closed loop vector mode provides the best performance for speed and torque control;
especially in low speed, high torque applications, including full torque at zero speed. The
SPX is required for closed loop control with a speed or position feedback device. The closed
loop ID run is similar to the open loop mode ID run.
PM Motor Control Operations
The SPX control can be used to control a synchronous PM motor open loop, or closed loop
with a resolver or absolute encoder. Best low speed, high torque performance is achieved
with a position feedback device. The High Performance Multi-purpose application has a
selection for PM motor control. The PM motor Encoder ID run determines the zero position of
the rotor and stores it to a parameter for use when the load is connected.
Sequence of Operation to Commission an Induction Motor
1. Read and follow all safety warnings and cautions in this manual.
2. At installation ensure:
●
That the SVX9000/SPX9000 and motor are connected to ground.
●
That the utility and motor cables are in accordance with the installation and
connection instructions as detailed in Chapter 3 — Power Wiring.
●
That the control cables are located as far as possible from the power cables as
detailed in Chapter 4 — Control Wiring and Table 3-1. That control cable shields are
connected to protective ground. That no wires make contact with any electrical
components in the SVX9000/SPX9000.
●
That the common input of each digital input group is connected to ground or +24V of
the I/O terminal supply or an external supply as detailed here and Figure 4-6.
3. Check the quality of the cooling air as detailed in Chapter 2 — Mounting.
4. Check that moisture has not condensed inside the SVX9000/SPX9000.
5. Check that all START/STOP switches connected to the I/O terminals are in the STOP
state.
6. Connect the SVX9000/SPX9000 to the utility and switch the power on. For the initial
power up you will enter the Start-Up Wizard, which will guide you through application
selection and basic parameter setup. See the Start-Up Wizard section at the end of
Chapter 5 — Menu Information for more information. After completing the Start-Up
Wizard, proceed to step 8. If this is not the initial power up, the keypad will default to the
Operate Menu. Depress the ENTER button for 2 seconds to enter the Parameter Menu.
Proceed to step 7.
