You can select the input specifications of terminal 2
(0 to 5V, 0 to 10V, 0 to 20mA) and input specifications
of terminal 1 (0 to ±5V, 0 to ±10V).
To change the terminal 2 to the voltage input
0 to 7,
1 specification (0 to 5V/ 0 to 10V), turn OFF (initial
10 to 17
status) the voltage/current input switch 2. To change
it to the current input (0 to 20mA), turn ON the
voltage/current input switch 2.
Override and reversible operation can be selected.
Set the ratio of added compensation amount when
100% 0 to 100%
terminal 2 is the main speed.
Set the ratio of added compensation amount when
75% 0 to 100%
terminal 4 is the main speed.
Set the bias side compensation value of override
50% 0 to 200%
function.
Set the gain side compensation value of override
150% 0 to 200%
function.

The primary delay filter time constant for the analog
1 0 to 8 input can be set.
A larger setting results slower response.
Set the time constant of the primary delay filter
0 to 5s,
9999 relative to the external speed command (analog input
9999
command).
Set the time constant of the primary delay filter
0 to 5s,
9999 relative to the external torque command (analog
9999
input command).
0 to 5s, Second function of Pr. 822 (valid when the RT
9999
9999 terminal is on)
0 to 5s, Second function of Pr. 826 (valid when the RT
9999
9999 terminal is on)
This function provides speed command by analog
input (terminal 2) with offset and avoids frequency
100% 0 to 200%
command to be given due to noise under 0 speed
command.
You can select the reset input acceptance, disconnected
PU (FR-DU07
0 to 3,
detection function and PU stop function.

14 to 17 For the initial value, reset always enabled, without
disconnected PU detection, and with PU stop
function are set.
0 Without fault code output
0 1 With fault code output
2 Fault code output at fault occurrence only
0 Write is enabled only during a stop
1 Parameter write is disabled.
0
Parameter write is enabled in any operation mode
2
regardless of operating status.
0 Both forward and reverse rotations allowed
0 1 Reverse rotation disallowed
2 Forward rotation disallowed
Description
