1) Setpoint values sent via Modbus will be ignored if DI3 is active.
2) P-15 = 4, 5, and 6 requires an enable signal (start command) via Modbus and at
DI1. Digital reference values sent via Modbus will be ignored in this case.
It will only be possible to use UP and DOWN to set a setpoint value.
3) Setpoint values sent via Modbus will be ignored if DI2 is active.
n.F. = No function. When configured this way, the control terminals "n.F." will
have no function whatsoever!
￫
If Modbus RTU is being used, there must always be an enable
signal (ENA) present at DI1 control signal terminal (or DI2 =
ENADIR) before the enable signal sent via Modbus RTU will be
accepted, ￫ Figure 5, page 12.
The activated operating direction will depend on the digital input being driven
(DI1, DI2) and on the value in command ID1, bit 1.
