“Rules to navigate menus,” to check and/or change the speed setting.
SPEED-ACCURACY MENU
Press the SPEED key (or press the CONFIG key and then the SPEED key) to display the menu
(Figure 4-1).
• FAST: Sets speed to 0.01 PLC and sets display resolution to 3½ digits.
• MED: Sets speed to 0.10 PLC and sets display resolution to 4½ digits.
• NORMAL: Sets speed to 1.00 PLC and sets display resolution to 5½ digits.
• HI ACCURACY: Sets speed to 10.00 PLC and sets display resolution to 6½ digits.
