Self-Lock means the actuator can hold its position by mechanical friction without motor power.
3. Reference Data
3.1 Voltage Vs Speed
Graph of speed change at no load according to input voltage. This data includes error and is for reference only.
Note
Voltage Vs Speed data was tested at Goal Current 800. This data includes about +/-15% error.
3.2 Voltage Vs Stall Force
Stall Force measured at 800mA according to input voltage. This data includes error and is for reference only.
Note
Voltage Vs Stall Force data was tested at Goal Current 1600. Each Force value has an error of +/- 15%.
Caution
Stall force is for reference only. To prevent product damage, use according to rated load in actual application.
3.3 Goal Speed Vs Speed
Shows no load speed change according to Goal Speed Parameter value at Goal Current 800. At less than rated load, the time to reach maximum speed varies depending on the load.
Note
Goal Speed Vs Speed data was tested at Goal Current 800.
3.4 Goal Current vs Stall Force
Shows mightyZAP's Stall Force for each Goal Current value. Stall Force was measured at minimum speed to reflect only current-based force.
TIP
This data shows motor force. It is recommended to set Goal current to 3x the actual load. The smaller the difference between actual load and motor force, the slower the speed. If equal, the motor will not move.
Caution
Each Stall Force value has an error of +/- 15%. Red-marked areas have large error due to internal load and heat, so use for reference only. If continuous load causes current over 1A, the current value will gradually drop and stabilize at 1A.
Double load setting
mightyZAP can be used up to 2x load. For 2x load, set Duty Rate to 20% or less. **ex>
Load Goal Current Duty rate Load Goal Current Duty Rate 20N(Rated) 800 Max. 50% 35N(Rated) 800 Max. 50% 40N(Max) 1600 Max. 20% 70N(Max) 1600 Max. 20%
3.5 Goal Current vs Speed at Rated Load
Shows mightyZAP's speed change for each Goal Current value at rated load.
TIP
Goal Current Vs Speed data was measured at rated load.
Caution
Speed data has about +/-10% error. Red-marked areas are where Stall Force and rated load are similar, so mightyZAP may not move. Use for reference only.
