PARAMETERS
4.3 Instructions
(1) Acceleration/deceleration time
When the frequency is set with the digital input signal, the acceleration/deceleration time is the period
of time required to reach the "acceleration/deceleration reference frequency" set in Pr. 20. This is the
same as when using the analog signal input.
(2) There are the following restrictions on the digital input signal:
•
When the signal is used to enter a BCD code, 0AH to 0FH entries are ignored during operation and
the previous inputs are used to continue operation.
(3) When the 12-bit digital input is valid (Pr. 304 setting is other than "9999"), the signals below are made
invalid.
1) FR-A500(L)/F500(L) series
Terminal assignment of input signal is determined according to Pr.180 to Pr.186 (input terminal func-
tion selection).
Signal Name Description Remarks
