6. Function Description
6-13
1.9) Prohibit FWD (Prohibition of forward rotation) / Prohibit REV (Prohibition of reverse rotation)
If Prohibit FWD or Prohibit REV is set, it prohibits forward or reverse rotation, respectively. If Prohibit FWD is used,
speed command becomes 0 when it has positive value. Similarly, If Prohibit REV is used, speed command becomes 0
when it has negative value.
(Example)
When multi-function input terminal P1 is set to
“
prohibit FWD
”
and P2 to
“
prohibit REV
”
the following
diagram will be shown.
1.10) Proc PID Dis (Process PID disabled)
This function is used to disable the Process PID controller. If Proc PID Enb at the CON_23 is Terminal and also this
terminal is ON, the output of Process PID controller becomes zero. Otherwise, Process PID controller generates its
output depending on the controller operation.
‘
Proc PID Enb
’
at CON_23 determines whether this function is used or
not. The setting for this code is as follows.

‘

at CON_23 blocks the output of Process PID controller and
‘
Enable
’
at CON_23 enables the Process PID
controller. If
‘
Terminal
’
is set, the multi-function terminal set to
‘
Proc PID Dis
’
determines whether the output of
Process PID controller is enabled or not. To prevent the saturation of Process PID controller, Process PID controller is
enabled only if the multi-function input terminal is set to
‘
Proc PID Dis
’
and its terminal input is OFF and operation
command is
‘
ON
’
. Process PID controller does not work if operation command is not ON or
‘
Process PID Disable
’
is not
set. Truth table is as follows.
