E6581295⑥
4.2. Network Grounding
Please note the following points regarding the grounding of a DeviceNet network.
- Do not connect the G/E terminal to a power ground or any other potential
noise-producing ground connection (such as a drive’s “E” terminal). Connect to a close,
clean ground to provide RF termination of the DeviceNet cable.
- Do not make connections to unstable grounds (paint-coated screw heads, grounds that
are subjected to inductive noise, etc.)
To prevent ground loops, the DeviceNet network should be earth grounded in only one
location. No significant current flow between V- and earth ground may occur via any
device other than a power supply under normal operating conditions.

5.1. f851: Communication Loss Action Setting (Network breaks)
This parameter sets up the VF-AS1/PS1 response to a loss of communications with the
DeviceNet network.
0: Stop and Communication release
The inverter decelerates the motor to a stop and gives an alarm (the leftmost LED
flashes). Commands entered through the network are canceled, and the commands
set with parameters cmodand fmodbecome effective.
When communications are restored, the alarm is turned off.
1: None
The inverter remains in the state where it was when the problem arose, and it gives an
alarm.
2: Deceleration stop
The inverter decelerates the motor to a stop and gives an alarm. Commands
entered through the network are not canceled.
3: Coast stop
The inverter issues a command for a frequency of 0Hz and gives an alarm.
Commands entered through the network are not canceled.
4: Emergency stop
The error message err8is displayed. Commands entered through the network are
not canceled.
When communications are restored, the inverter is not restored to working order and
the error message err8does not disappear until the inverter is reset.
5: Preset speed operation command
Refer to Section 5.2
5.2. f852: Preset speed operation selection
If the communication loss action (parameter f851) is set to 5 (preset speed command),
the VF-AS1/PS1 will run at a preset speed as set up by this parameter in the case of a
communication loss (with alarm). Commands entered through the network are not canceled.
For example,
If the inverter is set as described below,
f851= 5 (preset speed operation command)
f852= 8 (preset speed operation frequency 8)
f287(preset speed operation frequency 8) = 10 (10Hz)
Operation is carried out as follows.

*1: Preset speed operation can be performed at up to 15 different frequencies (preset
speed operation frequencies #1 to #15) specified by combining preset speed 1 to
preset speed 4. To perform preset speed operation, the “Command priority” option
and the “Run/Stop” bit must be set to 1.
Example: To run the motor in the reverse direction at preset speed operation
frequency #7 (sr7)
“10000110 00000111” = 0x8607 (hexadecimal)
If one of the bits for “Preset speed #1” to “Preset speed #4” is set to 1, priority is given
to preset speed operation even though the “Frequency link” bit is set to 1, and therefore
operation is not performed by “Frequency link”.
*2: Jog operation has higher priority than preset speed operation. If the operation
frequency is higher than the jog run frequency, however, jog operation is not carried
out.
