• Parameter Setting Example: When the Electronic Gear is Disabled and an SVA-01 Module is Used

Note: When motion fixed parameter 4 (Reference unit selection) is set to pulse, the electronic gear is

invalid.

When the electronic gear is disabled, n of the speed unit 10

n

reference units/min is 3. Therefore, the speed unit is:

[10

n

reference units/min] = [10

3

pulse/min] = [1000 pulses/min]

To convert the motor rated speed into pulses,

Rated motor speed [rotations/min]

× (Number of pulses per motor rotation [pulse/rotation] × multiplier)

= 3000

× (16384 × 4) = 196608000 [pulses/min]

Because the speed unit is 1000 pulses/min,

196608000 [pulses/min] = 196608 [1000 pulses/min]

• Parameter Setting Example: When the Electronic Gear is Disabled and a Built-in SVB, SVB-01, PO-01, or

SVR Module is Used

Note: When motion fixed parameter 4 (Reference unit selection) is set to pulse, the electronic gear is

invalid.

When the electronic gear is disabled, n of the speed unit 10

n

reference units/min is 3. Therefore, the speed unit is:

[10

n

reference units/min] = [10

3

pulses/min] = [1000 pulses/min]

To convert the motor rated speed into pulses,

Rated motor speed [rotations/min]

× Number of pulses per motor rotation [pulses/rotation]

= 3000

× 65536 = 196608000 [pulses/min]

Because the speed unit is 1000 pulses/min,

196608000 [pulses/min] = 196608 [1000pulses/min]

Motion fixed parameters other than those mentioned in the examples may be required to be correctly set for the correct
axis motions.
For details on each parameter and information on how to set them in accordance with the connected machine, refer to the
relevant motion module manual.

Motion Fixed Parameters
• No. 4: Reference unit selection = pulse
• No. 22: Pulse counting mode selection = A/B

× 4 (× 4)

• No. 34: Rated motor speed = 3000 rotations per min
• No. 36: Number of pulses per motor rotation (before multiplication) = 16384

pulses/rotation

Motion Fixed parameters
• No. 4: Reference unit selection = pulse
• No. 34: Rated motor speed = 3000 rotations/min
