Description
Torque command by terminal 1
analog input
Torque command by parameter
Pr. 805 or Pr. 806 setting
(−400 % to +400 %)
Torque command by using CC-
Link (FRA7NC)
Digital input from the option
(FR-A7AX)
Torque command by using CC-
Link (FR-A7NC)
Digital setting of the torque com-
mand can be made by setting
Pr. 805 or Pr. 806. (Setting from
communication option, etc. can be
made.) In this case, set the speed
limit value to an appropriate value
to prevent overspeed.
Use the speed command value
during speed control as speed
limit.
According to Pr. 808 and Pr. 809,
set the speed limit in forward and
reverse rotation directions individ-
ually.
The analog voltage of the terminal
1 input is used to make speed
limit. For 0 to 10V input, set the
forward rotation speed limit. (The
reverse rotation speed limit is Pr. 1
Maximum frequency.)
For −10 to 0V input, set the
reverse rotation speed limit. (The
forward rotation speed limit is Pr.
1 "Maximum frequency".) The
maximum frequency of both the
forward and reverse rotations is
Pr. 1 "Maximum frequency".
Set the speed limit level during
forward rotation.
(valid when Pr. 807 = 1)
Set the speed limit level during
reverse rotation.
(valid when Pr. 807 = 1)
The setting is the same as that of
the torque limit in the forward
rotation direction.
