Output Data Details

Word address
Bit 15
Signal name Rotational speed reference data
Content
Communications data = Rotational speed reference x 2
* The speed scale is assigned with the message function. For instructions on how to
change it, refer to Chapter 6 Message Communications.
* The units for the rotational speed reference are set in n035/o1-03 (frequency reference
setting and display units).
* Setting example (providing a reference of 1,800 r/min):
When the speed scale value is "0" and the number of motor poles is set in n035/o1-03
(so units are r/min):
1,800 r/min → 1,800 x2
Note 1. In this manual, the parameter location for the 3G3MV is written ahead of the parameter lo-
cation for the 3G3RV/3G3PV/3G3FV, so "n035/o1-03" indicates a parameter location of
n035 for the 3G3MV and parameter location of o1-03 for the 3G3RV/3G3PV/3G3FV.
Note 2. Under the DeviceNet protocol, the unit for the speed reference is fixed as r/min. The number
of motor poles (2 to 39) must be set in parameter n035/o1-03 (frequency reference setting
and display units) when using DeviceNet (open network).
Note 3. If the setting in not within the proper range, the previous data will be retained and the des-
ignated rotational speed will not be entered.

Signal name Rotational speed monitor data
Content
Communications data = Rotational speed monitor x 2
* The speed scale is assigned to the message function. For instructions on how to
change it, refer to Chapter 6 Message Communications.
* The unit for the rotational speed monitor is set in n035/o1-03 (frequency reference set-
ting and display units)
* Data conversion example:
When the speed scale value is "0" and the number of motor poles is set in n035/o1-03,
and the read data is 03E8 hex:
03E8 hex → 1,000 → 1,000/2

a: Speed scale value of Class 2A, Instance 01, Attribute 16 (Initial value: 0)
(Setting range: 0 to the rotational speed at maximum frequency)

→ 1,800 → 0708 hex
0: Normal, 1: Fault
0: Stopped, 1: Running forward
