f = (5000 - 500) ÷ 30 steps = 150 Hz
With 30 steps:
t = 300 ms ÷ 30 steps = 10 ms
f = (5000 - 500) ÷ 60 steps = 75 Hz
With 60 steps
t = 300 ms ÷ 60 steps = 5 ms

1.5 Hz to 9.8 KHz [K1 to K9800 (units: Hz)] (Max. error near 9.8 kHz approximately -0.9 kHz)
* Set “K1” to specify 1.5 Hz.
48 Hz to 100 KHz [K48 to K100000 (units: Hz)] (Max. error near 100 kHz approximately -3 kHz)
191 Hz to 100 KHz [K191 to K100000 (units: Hz)] (Max. error near 100 kHz approximately -0.8 kHz
(*3): Acceleration/deceleration time (ms) “K constant”
With 30 steps: K30 to K32767
With 60 steps: K36 to K32767
(*4): Target value “K constant”
K-2147483648 to K2147483647
Number of acceleration/deceleration steps
0: 30 steps
1: 60 steps (Can be specified for only Ver. 2.0 or later.)
