Step 5: Start-up Checklist
• This checklist supports the basic start-up menu option. See Start-up
Routines on page 46 for information on other start-up routines.
• A HIM is required to run the basic start-up routine.
• The basic start-up routine can modify parameter values for analog and
digital I/O. Refer to Common I/O Programming Changes on page 48 .
Prepare For Drive Startup
1. Verify the input supply voltage.
2. Check the output wiring.
3. Check the control wiring.
4. Connect a HIM to DPI Port 1 or 2.

Topic Description
Type Incremental, dual-channel
Supply 5V/12V Configurable ±5%
Quadrature 90° ±27°
Duty Cycle 50% +10%
Requirements Encoders must be line driver type, quadrature (dual channel) or pulse (single channel), single-
ended or differential and capable of supplying a minimum of 10 mA per channel. The encoder
interface board accepts 5V or 12V DC square-wave with a minimum high state voltage of 3.5V
DC (5V mode) and 7.0V DC (12V mode). Maximum low state voltage is 1V DC (for both 5V and
12V modes). Maximum input frequency is 250 kHz.
ATTENTION: Power must be applied to the drive to perform the following
start-up procedure. Some of the voltages present are at incoming line potential.
To avoid electric shock hazard or damage to equipment, only qualified service
personnel can perform the following procedure. Thoroughly read and
understand the procedure before beginning.
