5.1.2 Parameter Setting (High-Order Controller)
If the simple absolute unit is purchased separately and connected to an existing controller, one user
parameter must be set. (If the simple absolute unit was ordered together with the controller, this parameter
is set at the factory prior to the shipment.)
* You need the PC software or teaching pendant to set user parameters.
(1) ACON or PCON
Changes to be made
User parameter No. 83 Specify ABS unit: ‘1’ (Used)
(2) PSEL
Changes to be made
‚ Axis-specific parameter No. 38 “By encoder ABS/INC type”: Specify ‘1’ (ABS).
‚ Axis-specific parameter No. 46 “ABS unit usage selection”: Specify ‘1’ (Used).
Caution About Battery Charge and Discharge
Please have the battery charged for more than 72 hours before using for the first time or after replacing
with a new one.
The battery gets charged while the controller is supplied with 24V power.
It is possible to retain the encoder data for the duration shown below for each hour of battery charge.
Leaving the controller power off for more than the data holding time will lead to a loss of the data. Have
the battery charged as early as possible.
There is life to the battery and the duration for data holding will decrease. Replace the battery if you
confirm an extreme drop in data holding time even with enough charge time.
(Note) Data Holding Time *Followings are the reference values of time assuming the battery is new.
Setting of encoder maximum rotation speed 100 (75) 200 (150) 400 (300) 800 (600)
Data holding time per hour of battery charge
time (reference)
6.6H 5.0H 3.3H 1.6H
Holding time when fully charged (reference) 20 days 15 days 10 days 5 days
(Example) From Monday to Friday: charge for 8 hours per day, discharge for 16 hours,
Saturday and Sunday: use with discharge
• If 800 [RPM] setting;
Full charge amount : 24 [h] × 5 [day] = 120 [h]
Total charge amount : 8 [h] × 1.6 [h] × 5 [day] = 64 [h]
Total discharge amount : 16 [h] × 5 [day] + 48 [h] = 128 [h]
→ It is necessary to have a full charge in 10-day pitch if starting on Monday.
• If 400 [RPM] setting;
Total charge amount : 8 [h] × 3.3 [h] × 5 [day] = 132 [h]
Total discharge amount : 16 [h] × 5 [day] + 48 [h] = 128 [h]
→ It is not necessary to have a continuous full charge if starting on Monday.
4-hour charge is stored every week.
* The upper limit of power storage is a reference value for holding time after continuous battery charge.
