Table 6.9 IFIELD-MODULE Terminals on the ICE-FMP Board (Motor Field Module)
Terminal Description
FMO+ Field Module Output, positive, to motor field.
FMO- Field Module Output, negative, to motor field.
FMSI Field Module Safety Input: Jumpered to FMSO. FMSI and FMSO are always jumpered
together unless there is a requirement for a mechanical safety contact to break
between the load and the field module.
FMCI Field Module Current Input: When load current is higher than 10A, jumper FMCI to
FMHC. For load current less than 10A, leave both FMCI and FMHC open.
FMHC Field Module High Current: See FMCI.
FMS1 Field Module Snubber 1: When used as a Motor Field Module, an RC filter network
(RM & CM) is connected between FMS1 and FMS2. FMS1 is also jumper to FMLD.
FMS2 Field Module Snubber 2: Connect to RC filter (CM) see FMS1.
FMLD Field Module Load Diode: FMLD is connected to the cathode of a diode on the ICE-
FMP board. FMLD is also jumpered to FMS1.
FMSO Field Module Safety Output: Jumpered to FMSI. (see FMSI)
FMX1 AC power input to Field Module (70 VAC min, 300 VAC max)
FMX2 AC power input to Field Module (70 VAC min, 300 VAC max)
