Caution

Use at rated load as much as possible. When applying max applicable load (2x rated load), set Goal current to 1600(1.6A) and Duty cycle to under 20%.

2.8 Self Lock Feature

Tip

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. Data includes error, use as reference.

Note

Voltage Vs Speed data tested at Goal Current 800. Data includes about +/-15% error.

3.2 Voltage Vs Stall Force

Stall Force measured at 800mA according to input voltage. Data includes error, use as reference.

Note

Voltage Vs Stall Force data tested at Goal Current 1600. Each Force value error is +/- 15%.

Caution

Stall force is for reference only. To prevent product damage, use at 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, time to reach max speed varies by load.

Note

Goal Speed Vs Speed data tested at Goal Current 800.

3.4 Goal Current vs Stall Force

Shows mightyZAP Stall Force for each Goal Current value. Stall Force 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 actual load. If the difference between actual load and motor force is small, speed decreases. If equal, motor does not move.

Caution

Each Stall Force value error is +/- 15%. Red-marked areas have large error due to internal load and heat, use as reference only. If continuous load causes current over 1A, current value will decrease and stabilize at 1A.

2x load setting

mightyZAP can be used up to 2x load. At 2x load, set Duty Rate to under 20%. 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 speed change for each Goal Current value at rated load. ![[27_goalcurrentVSspeed 1.png|700]]

TIP

Goal Current Vs Speed data measured at rated load.

Caution

Speed data has about +/-10% error. Red-marked areas are where Stall Force and rated load are similar, mightyZAP may not move. Use as reference only.
