6.7 Acceleration/Deceleration Parameter High-speed Switching Function
• Setting Example 1: Switching three banks of members Pn80B, Pn80E, and Pn80C
Pn900 = 3
Pn901 = 3
Pn902 = 80Bh
Pn903 = 80Eh
Pn904 = 80Ch
• Setting Example 2: Switching two banks of members Pn836, Pn83C, and Pn838
Pn900 = 2
Pn901 = 6
Pn902 = 836h
Pn903 = 836h
Pn904 = 83Ch
Pn905= 83Ch
Pn906 = 838h
Pn907 = 838h
 Application Notes
• If Pn900 (Number of Parameter Banks) or Pn901 (Number of Parameter Bank Members) is
set to 0, the bank function will be disabled.
• If one parameter is registered for more than one bank member definition, the bank data of the
biggest bank member definition parameter number will be applied.
• The acceleration/deceleration parameter high-speed switching function is enabled only while
DEN = 1 (distribution completed). The parameters will not switch while DEN = 0 (distributing).
However, this does not apply to changing the S-curve acceleration/deceleration ratio
(Pn846).
• In the following cases, error A.04A (Parameter Setting Error 2) will occur when the power
supply is turned back ON or CONFIG command is executed.
• One 4-byte parameter is not registered for two consecutive bank members.
• The total number of bank data entries exceeds 64 (Pn900 × Pn901 > 64).
• If a parameter that is not allowed to be a bank member is registered, the bank data of the
parameter-registered member will become invalid.
• Bank data that exceeds the setting range of the registered bank member parameter will be
clamped to a value within the setting range.
• If a bank number larger than the bank number set in Pn900 is specified (BANK_SEL1 ≥
Pn900), the parameter bank will not switch and the currently active bank will be used.
• The parameters Pn920 to Pn95F will not be stored in the non-volatile memory. They need to
be set every time the power is turned ON.
