CX-1010 START UP GUIDE SK1657 RevA

CX-1010 Start Up Guide Introduction The CX-1010 motion controller is used in conjunction with various types of motor drives for precision control of motors in industrial applications. In most applications, its signal voltage output is used as a speed command input by the motor drive. It requires a feedback input signal, usually a frequency, indicating motor or process speed. Based on the setpoint and feedback inputs, the CX-1010 adjusts the speed command output to maintain the required motor RPM.
Basic Wiring WARNING The CX-1010 should only be installed by a qualified electrician. Hazardous voltages may cause severe injury, death or equipment damage. The CX-1010 General Wiring Diagram illustrates the complete power and signal wiring for the CX-1010 control. Not all of the connections will be required for your application. Refer to the CX-1010 Technical Reference Manual for complete installation and wiring instructions.

Motor Drive Set Up In order to achieve desired system performance, the motor drive connected to the CX-1010's speed command output must be properly set up. Refer to your motor drive manual to assist you in making the following four motor drive adjustments: • Set the maximum speed adjustment on the drive to deliver 10% more speed than the expected maximum speed required for your application. • Set the acceleration and deceleration times to their fastest settings.

Speed Command Output Scaling In this section, the speed command mode, maximum signal voltage to the motor drive and voltage polarity will be set up. Set the output control mode for bipolar or unipolar operation: 1. If your application runs in one direction only, skip to step 4. 2. Go to MAIN MENU\SCALING\STANDARD SIGNALS\P3\. Enter CO Mode {CP 180} = Bipolar. 3. Skip to step 5. 4. Go to MAIN MENU\SCALING\STANDARD SIGNALS\P3\. Enter CO Mode {CP 180} = Unipolar.
Verify forward motor direction: 7. If motor is running in the forward direction, skip to step 9. 8. Rewire the motor leads for forward direction. Verify forward sensor polarity: 9. Go to MAIN MENU\SYSTEM MONITOR\STD SIGNALS MONITOR\P2\. 10. If FI2 Hz {MP 6} is a positive number, skip to step 12. 11. Rewire the feedback sensor polarity. 12. If your application is unipolar only, skip to step 24. 13. Place the control into “F-Stop”. Reverse Enter a direct mode setpoint for the reverse direction: 14.
Master Mode and Feedforward Scaling In this section, the master mode is scaled for engineering units. The feedforward is also scaled using the auto feedforward feature. Master mode scaling should be completed even if your end application is not master mode. The CX 1010 must convert the feedback frequency into engineering units (RPM, Feet/min, etc.). To do this, it must "know" the ratio between encoder lines and these units. This ratio is entered in two parts on page two of the STANDARD SIGNALS screen.
Follower Mode Scaling In this section, the follower mode is scaled for engineering units. Master mode scaling should be completed before proceeding with the follower mode scaling procedure. If it is in follower mode, the CX-1010 must convert the lead frequency into engineering units (RPM, Feet/min, etc.). To do this, it must "know" the ratio between encoder lines and these units. This ratio is entered in two parts on page one of the STANDARD SIGNALS screen.
