ASDA-A2  Chapter 5  Trial operation and Tuning 
Revision February, 2017                                                                      5-7 
5.4  Trial Run without Load (Speed Mode) 
Before the trial run without load, firmly secure the motor base so as to avoid the danger cause by 
the reaction of motor operation. 
Step 1: 
Set the control mode of the servo drive to speed mode. Set P1-01 to 2 as speed mode. Then, re-
power on the servo drive. 
Step 2: 
In speed control mode, the digital input settings of trial run are as follows: 
Digital Input  Parameter 
Setting Value 
Symbol  Function Description  CN1 Pin No 
DI1  P2-10 = 101  SON  Servo ON  DI1- = 9 
DI2  P2-11 = 109  TRQLM  Torque limit  DI2- = 10 
DI3  P2-12 = 114  SPD0  Speed command selection  DI3- = 34 
DI4  P2-13 = 115  SPD1  Speed command selection  DI4- = 8 
DI5  P2-14 = 102  ARST  Alarm reset  DI5- = 33 
DI6  P2-15 = 0  Disabled  Invalid DI function  - 
DI7  P2-16 = 0  Disabled  Invalid DI function  - 
DI8  P2-17 = 0  Disabled  Invalid DI function  - 
EDI9  P2-36 = 0  Disabled  Invalid DI function  CN7 = 2 
EDI10  P2-37 = 0  Disabled  Invalid DI function  CN7 = 3 
EDI11  P2-38 = 0  Disabled  Invalid DI function  CN7 = 4 
EDI12  P2-39 = 0  Disabled  Invalid DI function  CN7 = 5 
EDI13  P2-40 = 0  Disabled  Invalid DI function  CN7 = 6 
EDI14  P2-41 = 0  Disabled  Invalid DI function  CN7 = 7 
The above table disables the function of negative limit (DI6), positive limit (DI7) and emergency 
stop (DI8). Thus, the value of parameter P2-15 ~ P2-17 and P2-36 ~ P2-41 are set to 0 (Disabled). 
The digital input of Delta’s servo drive can be programmed by users. When programming digital 
input, please refer to the description of DI code. 
The default setting includes the function of negative limit, positive limit and emergency stop, 
therefore, after the setting is completed, if there is any alarm occurs, please re-power on the servo 
drive or switch ON DI5 to clear the alarm. Please refer to Chapter 5.2.
