b90 : External control operation mode 000: Forward/ Stop-Reverse/Stop
1.) b90 is only available when A00 = 001 (control from terminals TM2).
2.) When both forward and reverse commands are ON, output is stopped.
Parameter b90 = 000
(1). NPN input signal:
S1 (Forward/Stop)
S2 (Reverse/Stop)
COM (Common)
Parameter b90 = 001
(1). NPN input signal:
S1 (Run/Stop)
S2 (Forward / Reverse)
COM (Common)
Parameter b90 = 002
(1). NPN input signal:
Note:- In 3 wire control mode terminals S1-S3 are used , therefore parameters
b35 ~ b37 are ineffective.
