Mapping Detail

Run Fwd: forward rotation command (0=forward rotation off, 1=forward rotation on). Maps to inverter register 1007, bits 9 and 10. Run Fwd = 1 translates to inverter register 1007 bit 9 (direction) = 0 and bit 10 (run/stop) = 1. Note that if both the “Run Fwd” and “Run Rev” bits are on, then inverter register 1007 will not be changed from its previous value.

Run Rev: reverse rotation command (0=reverse rotation off, 1=reverse rotation on). Maps to inverter register 1007, bits 9 and 10. Run Rev = 1 translates to inverter register 1007 bit 9 (direction) = 1 and bit 10 (run/stop) = 1. Note that if both the “Run Fwd” and “Run Rev” bits are on, then inverter register 1007 will not be changed from its previous value.

Fault Reset: Inverter reset command (0=no action, 0→1 rising edge=reset). Maps to inverter register 1007, bit 13 (fault reset).

NetCtrl: Run/stop control source selection (0=local control, 1=network control). Maps to inverter register 1007, bit 15 (command priority).

NetRef: Speed reference source selection (0=local control, 1=network control). Maps to inverter register 1007, bit 14 (frequency priority).

Speed Reference: Inverter speed reference in RPM. Maps to inverter register 1008 (frequency command). Because the inverter always requires a frequency command value in units of Hz, the interface card applies an RPM-to-Hz conversion equation. The general RPM-to-Hz conversion equation is [RPM x number of motor poles / 120]. However, for simplicity the interface card always assumes that a 4-pole motor is in use, thereby reducing the applied conversion equation to [frequency command value = RPM / 30].
