Cyclic Data Access - Dout Mapping
If the SMV Control Word is used, the RUN and STOP commands are controlled as listed in Table 12.
Table 12: SMV Control Word RUN and STOP Events
BIT 0 - RUN FWD
BIT 1 - RUN REV
Action
0
0
STOP Method (Refer to P111)
0 -> 1

RUN FORWARD
0
0 -> 1
RUN REVERSE
0 -> 1
0 -> 1
NO ACTION / remains in last state

1 -> 0
RUN FORWARD
NOTE
If P112 (ROTATION) is set to FORWARD ONLY, the drive will not be able to run in the reverse
direction.
For the purpose of absolute clarity:
"0 -> 1" is the transition from 0 to 1 and "1 -> 0" is the transition from 1 to 0
5.4.3 P44x = 2, Network Frequency Setpoint
The Network Frequency Setpoint is represented as an unsigned Hz value. This mapping along with the use
of the correct Control Word Bits allows the drive frequency setpoint to be controlled from the network. This
mapping function uses unsigned scaled integer values.
Example:
Frequency Setpoint value to be transmitted from the network master = 33.5Hz.
The actual value transmitted to the drive must be 335 (0x014F).
