The Speed Override parameter (OW
target feed speed, in 0.001% units. Speed Override is set independently of Command Unit, Number
of Decimal Places, and other parameters.
Speed Override cannot be set for SVR (Virtual Motion Module).
A typical example of a Speed Override setting is shown below.
Setting Example
Output ratio 25%: 25 ÷ 0.01 = 2500
50%: 50÷0.01 = 5000
75%: 75÷0.01 = 7500
100%: 100÷0.01 = 10000
Speed Reference Parameter Settings (OL
500 (R/s) × 65536 (pulse/R)
= 37268000 (pulse/s)
1500 (R/min) × 65536 (pulse/R) ÷ 60 (s/min)
= 1638400 (pulse/s)
500 (mm/s)÷ 0.001
= 500000 (mm/s)
• Determined by feed speed and number of digits below
decimal point (0.001 in the above equation),
regardless of machine configuration.
900 (mm/min) ÷ 0.001 ÷ 60 (s/min)
= 15000 (mm/s)
* Determined by feed speed and number of digits below
decimal point (0.001 in the above equation), regardless
of machine configuration.
500 (R/s) × 65536 (pulse/R) ÷ 1000* × 60 (s/min)
= 1966080 (1000 pulse/min)
n
• "1000" = 10
1500 (R/min) × 65536 (pulse/R) ÷ 1000*
= 98304 (1000 pulse/min)
n
• "1000"= 10
500 (mm/s) ÷ 0.001 × 1000 × 60 (s/min)
= 30000 (1000 mm/s)
• Determined by feed speed and number of digits below
decimal point (0.001 in the above equation),
regardless of machine configuration.
900 (mm/min) ÷ 0.001 × 1000
= 900 (1000 mm/min)
• Determined by feed speed, regardless of machine
configuration.
1500 (R/min) ÷ 3000 (R/min) × 100(%) ÷ 0.01
= 5000 (0.01%)
• Determined by what percentage the feed speed is of
the rated speed.
