5. EH/EH2/SV series MPU supports high speed counters. C235 ~ C240 are program-interruption 1-phase high
speed counter with a total bandwidth of 20KHz, can be used alone with a counting frequency of up to 10KHz.
C241 ~ C254 are hardware high speed counter (HHSC). There are four HHSC in EH/EH2/SV series MPU,
HHSC0 ~ 3. The pulse input frequency of HHSC0 and HHSC1 can reach 200KHz and that of HHSC2 and
HHSC3 can reach 20KHz (1 phase or A-B phase). The pulse input frequency of HHSC0 ~ 3 of 40EH2 series
MPU can reach 200KHz, among which:
C241, C246 and C251 share HHSC0
C242, C247 and C252 share HHSC1
C243, C248 and C253 share HHSC2
C244, C249 and C254 share HHSC3
a) Every HHSC can only be designated to one counter by DCNT instruction.
b) There are three counting modes in every HHSC (see the table below):
i) 1-phase 1 input refers to “pulse/direction” mode.
ii) 1-phase 2 inputs refers to “clockwise/counterclockwise (CW/CCW)” mode.
iii) 2-phase 2 inputs refers to “A-B phase” mode.
