OPERATION 8. HOW TO USE APPLIED FUNCTIONS (PARAMETER)
(3) Transparent format
Reading method by the transparent format is designated the parameter No. 77(HOLD selection) as “0”.
Updating of the current position value (speed) is stopped while the current position HOLD signal is input (ON).
The current position value (speed) should be read at that time.
TS: Updating cycle of the current position value (speed) output
TS is able to change by the parameter No. 91 (Latch pulse cycle).
0: 0.352ms, 1: 17.58ms, 2: 35.16ms, 3: 1.406ms, 4: 4.219ms
5: 8.438ms, 6: 17.58ms, 7: 35.16ms, 8: 70.32ms, 9: 140.6ms
T1: Time from turning ON the current position HOLD input to stopping to update the current position value output.
T1
≦
4ms
T2: Time from turning OFF the current position HOLD input to starting to update the current position value output.
T2
≦
TS+4ms
(4) PC synchronization format
Reading method by the PC synchronization format is designated the parameter No. 77(HOLD selection) as “1”.
The current position value (speed) output updating occurs when the current position HOLD signal status
changes (leading edge or trailing edge). The host controller reads the current position value (speed) output
after being changed the current position HOLD signal.
T1: Time from changing the current position HOLD signal to stopping to update the current position value output.
T1
≦
4ms
Delay: Delay time from inputting the current position HOLD signal to completing to update the current position value.
The time is set by the parameter No.76 (
PC synchronization delay value
).
Setting range: 0 to 99ms

CAUTION Cautions for VS-5FX and VS-5FX-1
The “external origin set function (chapter No.8-9)” cannot be used when using the transparent or
PC synchronization format.
