Hint:
Put jumper to connect the internal 120 terminating resistor for CAN2 interface.
ID-COM module is not required when inter-controller CAN2 and J1587 lines are not used. In this case
connect Extension modules CAN1 directly to Extension modules port ID-COM on ID-DCU MARINE (9-pin
connector: 5=H, 9=L).
ID-SCM Speed control module
ID-SCM module is interface module for InteliDrive controller application. Module is mounted directly to ID-
DCU MARINE controller case. Module power supply: 8 to 36VDC.
Inputs
RPM1, RPM2: Two inputs for frequency (e.g. flow) measuring. Expected sensor is magnetic pickup – with
maximal frequency range up to 8 kHz. The output values SCM Freq1, SCM Freq2 calculation use setpoints
SCM unit: FreqRate1 and FreqRate2 - see below.
Closed jumper divides input frequency by 16 - recommended for higher frequency (>1000Hz) measuring.
Jumper position does not influence output value range.
RPM input nominal frequency range
IMP1, IMP2: Two impulse inputs for integral (e.g. consumption) measuring. It is expected NPN – open
collector (active) impulse sensor with maximal frequency range up to 60 Hz. Minimal pulse duration is 1ms.
The output values SCM Imp1, SCM Imp2 calculation use setpoints SCM unit: TransferRate1 and
TransferRate2 - see below.
