6.1 Parameter

ME0384-4A
[Position Command Primary Filter Time Constant (Parameter No. 55)]
No. Name Unit Input range
Default initial value setting
55
filter time constant
ms 0.0 to 100.0 0.0
Used when the value of "Acc/Dec mode" field in the position table is set to 2(First-order delay
filter).
This draws a more gentle acceleration/deceleration curve compared to trapezoidal patterns.
The shock at acceleration/deceleration is relieved, but the cycle time becomes longer.
Use for applications where minor vibrations to the workpiece during acceleration/deceleration
are to be avoided.
The amount of first-order delay is set by parameter No. 55 "Position command primary filter time
constant". The setting unit is ms and can be set from 0.0 to 100.0 in 0.1ms increments.
However, this is not reflected for jogging/inching operations via a PC or teaching pendant.
Caution
● In the following cases the first-order delay filter becomes disabled.
(1) When a position command or direct numerical value command with the first-order
delay filter is set during actuator operation.
(2) When using a rotary actuator in index mode.
(3) When parameter No. 55 is set to 0.
