5-4 Setup MN1853
Configuring Motor Resolution [ MR10 ]
EDIT
> SETUP > MOTOR > D–RES
Value: 36000 (fixed)
Range: N/A
– Axis One Drive Res –
–↑ 36000(Fixed) ↓–
The Drive Resolution is fixed at 36,000 as shown.
Configuring Motor Direction [ MDi ]
EDIT
> SETUP > MOTOR > DIR
Value: Positive
Range: Positive or Negative
– Axis One Motor Dir –
POSITIVE
Select value, press ENTER
Provides a convenient way to change the motor direction for a positive distance
command. When POSITIVE is selected as the motor direction, the EOT+ limit
switch should be wired so that moves in the plus direction will activate the switch.
When NEGATIVE is selected, the EOT+ limit switch should be wired so that
moves in the negative direction will activate the switch.
Configure Encoder If you are not using an encoder, set encoder mode to OPEN LOOP and skip to MECH.
Configuring Encoder Mode [ EMi ]
EDIT
> SETUP > ENC > MODE
Value: Closed Loop–PM
Range: Open Loop, Open–Stall,
Closed Loop, Closed Loop–PM
– Axis One ENC Mode –
–↑ CLOSED LOOP–PM ↓–
Select value, press ENTER
Open Loop The OPEN LOOP position will be displayed on the keypad.
Open–stall The OPEN LOOP position will be displayed on the keypad, and
the encoder will be used for stall detection. (See Following Error)
Closed Loop The actual encoder position is displayed on the screen. All
subsequent moves are calculated from this actual position. All
moves are based on encoder pulses. Stall detection is enabled.
Positioning resolution will equal the resolution of your encoder.
Closed Loop–PM Same as closed loop except for the post move position
maintenance of the last commanded position. Provides a
“pseudo–servo” operation for a stepper system. Closed Loop–PM
will not correct position while navigating menus with the keypad.
Use PM GAIN, PM VMAX, and IN–RANGE WINDOW parameters to specify position
maintenance tuning parameters.
Application Notes:
Following–error is still active while in CLOSED LOOP–PM mode. A following–error will
occur when the number of correction steps exceeds the following error value. This
allows the unit to signal a fault when the displacement cannot be corrected, i.e. an
obstruction. Ensure proper operation in Open Loop mode before Closed Loop–PM.
