Homing Offset - This parameter sets distance past the index marker at which the motor will stop.
The distance is set by the number of digital pulses that the control expects before stopping motor
rotation. The 23H control has 4096 digital pulses per resolver speed per revolution of the motor
shaft. The recommended minimum offset is at least 100 encoder counts to provide deceleration
distance to allow the motor to smoothly stop. The range of adjustment is 0-65535 counts.
Security Control Block
Security State - This parameter determines if a security code will be required to change protected
programming parameters. There are three levels of security code that may be imposed with this
parameter as well as the option to turn this function OFF. The three levels of security are LOCAL,
SERIAL AND TOTAL.
If set to LOCAL security, a security code must be entered before parameter changes can be made
from the keypad.
NOTE: THE USER CAN PRESS THE PROG KEY AND SCROLL THROUGH THE
PARAMETERS ALREADY PROGRAMMED BUT CAN NOT CHANGE THEM.
THE USER WILL BE PROMPTED FOR THE SECURITY ACCESS CODE
BEFORE THE CONTROL WILL ACCEPT A PARAMETER CHANGE.
If set to SERIAL security, a security code must be entered before parameter changes can be made
through the serial communication link.
NOTE: THE USER CAN PRESS THE PROG KEY AND SCROLL THROUGH THE
PARAMETERS ALREADY PROGRAMMED BUT CAN NOT CHANGE THEM.
THE USER WILL BE PROMPTED FOR THE SECURITY ACCESS CODE
BEFORE THE CONTROL WILL ACCEPT A PARAMETER CHANGE.
If set to TOTAL security, a security code must be entered from the keypad or the serial
communication link before changes can be made to protected parameters.
NOTE: THE USER CAN PRESS THE PROG KEY AND SCROLL THROUGH THE
PARAMETERS ALREADY PROGRAMMED BUT CAN NOT CHANGE THEM.
THE USER WILL BE PROMPTED FOR THE SECURITY ACCESS CODE
BEFORE THE CONTROL WILL ACCEPT A PARAMETER CHANGE.
Setting the Security State to OFF will defeat the security system. The factory setting for this
parameter is OFF.
Access Timeout - With any of the 3 types of security enabled, the security access code is
required before Parameter changes will be accepted in the Program mode. Assuming the security
code has been entered and parameters have been changed and accepted, the user can verify the
effect the parameter change(s) have on control operation by going to the display mode by pressing
the DISP key. If additional changes then need to be made, the Access Timeout feature allows the
