4.10 SAN Unit DIP Switch setting.
In a multiple SAN Unit system, it is necessary to address the SAN units for communication
purposes. The number is set using the DIP switch located on the front of the SAN unit. No
two units may share the same number, however units may be skipped or started from a num-
ber besides one. Typically units are numbered in sequential order. (ex. 1-31)
Note: When connected to a Multi Unit, the programmed sequence must not contain any spin-
dle(s) which are skipped or missing from the DIP switch setting procedure.
FIG. 4-10 Dip Switch settings
4.10.1 SAN Unit DIP Switch positions 1 ~ 3
{ DIP switch positions 1 ~ 3 are used for setting the special configuration features as defined in the
following explanation
{
{ DIP Switch 1 - CAL/Zero acceptance window selection.(in Firmware versions 1.03 and greater).
P ON - CAL/Zero acceptance = +/- 10 % of Full scale torque
P OFF - CAL/Zero acceptance = +/- 4 % of Full scale torque (Default)
{ DIP Switch 2 - Start input type selection. (Set “OFF” with Multi Unit)
P ON - Deadman - Start input must remain on for the entire fastening cycle.
(For Manual applications).
P OFF - Auto Start mode - Start input pulse initiates automatic cycle. (Default)
(Cycle starts and continues from start pulse)
{ DIP Switch 3 - Disable Motor Ramp Down.
P ON - Enables dynamic brake for motor speed changes.
- Used for applications which overshoot standard torque
- Will reduce Motor/Tool life
P OFF - Disables Dynamic brake during speed changes (Default)
(When set- up for “Dual Transducer” Function, DIP Switch 3 has an alternate function – ON sets the
controller as MASTER & OFF sets the controller as SLAVE – see 7.3.8 for more information)
NOTE: The SAN unit must be powered off and on again after any DIP switch change.
