 Setting Procedure
 STEP1
1.
Set Pn900 (Number of Parameter Banks) to m.
2.
Set Pn901 (Number of Parameter Bank Members) to n.
Set Pn900 and Pn901 so that Pn900 × Pn901 ≤ 64.
3.
Register bank member parameter numbers using parameters Pn902 to Pn910.
4.
To enable the bank function, execute the CONFIG command or turn the power supply
OFF and then ON again.
 STEP2
5.
Set the data of each bank in the parameter bank data area from the leading parameter
Pn920 in order as shown below.
Bank 0: Pn920 to Pn (920 + n – 1)
Bank 1: Pn (920 + n) to Pn (920 + 2n–1)
:
Bank m – 1: Pn {920 + (m – 1) × n} to Pn (920 + m × n – 1)
Note: 1. If parameters Pn900 to Pn910 set in STEP 1, 2, and 3 are saved in the non-volatile memory, carry out
STEP 5 only after turning the power ON the next and subsequent times.
However, if you turn the power supply OFF and then ON again after saving parameters Pn900 to Pn910 in
the non-volatile memory (i.e. with the bank function enabled), and start the operation without setting
parameters Pn920 to Pn95F, the operation will be carried out under the condition that all bank data is set
to 0 (zero) or the minimum setting.
2. If parameters Pn900 to Pn910 set in STEP 1, 2, and 3 are not saved in the non-volatile memory, carry out
STEP 1 to 5 each time the power supply is turned ON.
