D1-N Series Servo Drive User Manual Wiring
HIWIN MIKROSYSTEM Corp. 4-25
The formulas of time delay and the required maximum deceleration are as below:
(1) Time Delay (T) = (Smooth Factor X 8)/Sampling Rate
(2) Maximum Deceleration (Max. dec.) = Speed/T
Example:
Sampling rate is 16 KHz. Motor speed is 400 mm/s. Smooth factor is 100.
Time Delay (T) = (100X8)/16,000 = 0.05 s
Maximum Deceleration (Max. dec.) = 400/0.05 = 8,000 mm/s

(3) Timing of activating STO safety function
STO safety function is activated by SF1 and SF2 inputs. The relationship between the logic states of
SF1 and SF2 inputs and STO safety function are described in table 4.8.3.
