FX Series Positioning Controllers Parameters 4
4-15
PARA. 10: Interpolation time constant
Set the time required to achieve the speed specified by the program. (The bias speed is always
regarded as "0".) This parameter is valid while interpolation control is performed in the FX
2N
-
20GM.
*1 In the FX
2N
-10GM, acceleration/deceleration time is set to the value set in this parameter
when the cod 01/ cod 31 command is used.
The parameters explained on the previous page have the relationship shown in the figure below.
*1 The acceleration time indicates the time required to achieve the maximum speed. Accord-
ingly, when all of the command speed, the zero return speed and the jog speed are equiva-
lent to or less than the maximum speed, the actual acceleration time becomes shorter.
*2 The interpolation time constant is always fixed while interpolation control is performed.
Accordingly, the gradient of acceleration/deceleration varies depending on change in the
command speed. If the speed is not specified, "100 kHz" is automatically set to the FX
2N
-
20GM and "200 kHz" to the FX
2N
-10GM. In the FX
2N
-10GM, multistep speed operation is
performed.
The parameters explained on the previous page have the relationship shown in the figure below.
