Section 2 Installation This section covers all instructions for proper mounting and wiring of the Baldor Series 23H servo control. All tools required for normal installation should be available from any electrical service technician. If problems arise after installation, please refer to Section 4 Diagnostics and Troubleshooting.
FOR ALL CONTROL CATALOG LISTINGS. AC Line Impedance The Baldor Series 23H servo control requires a minimum line impedance of 3%. If the incoming power line does not have a minimum of 3% impedance, the addition of a line reactor will provide the needed impedance in most cases.

MN723H-10/95 11/28/95 1:14 AM Page 97 (Black plate) Improper Motor Operation Wrong Response to Speed Commands Input common mode voltage may be exceeded. Maximum common mode voltage at terminals J1-4 and J1-5 is ± 15 volts relative to chassis common. Connect control input source common to the control common to minimize common mode voltage.

MN723H-10/95 11/28/95 1:14 AM Page 98 (Black plate) Speed Prop Gain Parameter This parameter is located in the Level 1, Brushless Control Block. The Speed Prop Gain parameter is normally preset or auto-tuned. This gain may be increased or decreased to suit the application. Increasing the Speed Prop Gain parameter will result in faster response, excessive proportional gain will cause overshoot and ringing.
