4） Select the starting mode in【Start method】.
There are two starting method:
“Using HSC instruction”: If selecting this method, then it needs to execute HSC instruction
to start the HSC. Before executing HSC instruction, it doesn’t need to configure the
registers and execute HDEF instruction.
“Run directly at PLC startup”: If selecting this method, then the HSC will start
automatically after PLC power on without executing any instructions.
5） If user needs to use multiple PV mode, then check 【Enable multiple PVs】 and
continue to configure all PV values and related ‘Value’ and ‘Interrupt subroutine’. If
checking【Update PV and quantity】, then it can adjust the value in【Quantity】to modify
the number of PV.
6） If user needs to use single PV mode, then check 【Update preset value(PV)】 in
‘Single PV settings’ and modify the PV value and related interrupt subroutine.
7） For other options, please refer to the descriptions to HSC.
3.2.4 How to use high speed pulse output
MK also provides 4 high speed pulse outputs(Q0.0,Q0.1,Q0.4andQ0.5)and all support
PTO(pulse train) and PWM(pulse width modulation) output.The highest frequency of each
series of CPU is as follows(The resistor of load should be less than 3KΩ).

For position control instruction,MK070E have one position output channel for every high
speed pulse output .Meanwhile one position enable control bit in SM area.

Position output channel output motor position signal. Forward is 0, rollback is 1.
Position output enable control bit forbid or allow the involved output channel. The position
enable control bit have highest priority. If it is forbidden, position control instruction won’t
output position control signal. The involved output channel will be used as common DO.
