Remark: 

(1)  t1: ENA must be ahead of DIR by at least  5us, logic HIGH as valid.  Generally  

ENA+ and ENA- is NC (not connected). 

(2)  t2: DIR must be ahead of PUL effective falling edge by 5us to ensure correct direction; 

(3)  t3: Pulse width not less than 1.2us; 

(4)  t4: low level width not less than 1.2us. 

 

11. Wire Connection 

(1)  In order to improve driver noise rejection, it is recommended to use twist ed 

pair shield cable. 

(2)  To prevent noise incurred in pulse/dir signal, Pulse/direction signal wires 

and motor wires should not be tied up together.  It is better to separate 

them by at least 10 cm, otherwise the motor noise will easily disturb pulse 

direction signals, motor position error, system instability and other types of 

failure. 

(3)  If a power supply serves several drivers, separate connections drivers is 

recommended instead of daisy-chaining. 

(4)  It is prohibited to pull and plug connector P2 while driver is powered ON, 

as there is still high current flowing through coil even when motor is 

stopped.    Pulling and plugging P2 with power on will cause extremely high 

voltage surge EMF, destroy the dirver.

TWELVE MONTH LIMITED WARRANTY                                               

FULLING MOTOR 

Co., Ltd. warrants its products against defects in materials and 

workmanship for a period of 12 months from receipt by the end-user. During the warranty period, 

FULLING

 will either, at its option, repair or replace products which prove to be defective. 

 

EXCLUSIONS                                                                                                                           

The above warranty shall not apply to defects resulting from: improper or inadequate handling by 
customer; improper or inadequate customer wiring; unauthorized modification or misuse; or 
operation outside of the electrical and/or environmental specifications for the product. 

 

OBTAINING WARRANTY SERVICE                                                                                     

To obtain warranty service, a returned material authorization number (RMA) must be obtained 

from customer service at e-mail: 

 before returning product for service. 

Customer shall prepay shipping charges for products returned to

 FULLING

 for warranty service, 

and 

FULLING

 shall pay for return of products to customer.  

 

WARRANTY LIMITATIONS                                                                             

FULLING

 makes no other warranty, either expressed or implied, with respect to the product. 

FULLING

If your product should fail during the warranty period, e-mail customer service at 

 

       

to obtain a returned material authorization number

 

before returning 

product for service. Please include a written description of the problem along with contact name 

and address. Send failed product to distributor in your area or: 

Changzhou Fulling motor Co.,Ltd

.  

66 Zhujiang Road ChangZhou city JiangSu Province

 China.

 Also enclose information 

regarding the circumstances prior to product failure.
