Chapter 5  Trial Operation and Tuning  ASDA-B2 
5-8     Revision May, 2018 
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. 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  - 
DI9  P2-36 = 0  Disabled  Invalid DI function  - 
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 is 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.
