Chapter 7 Servo Parameters|ASDA-A&A+ Series 
Revision April 2009    7-59 
P2 - 28 
 
GUT  Gain Switching Time Constant  Communication Addr.: 021CH
Default: 10  Related Section: N/A 
Applicable Control Mode: ALL   
Unit: 10ms 
Range: 0 ~ 1000   
Settings: 0: Disabled 
This parameter is used to set the time constant when switching the smooth gain. 
 
P2 - 29 
 
GPE  Gain Switching Condition  Communication Addr.: 021DH
Default: 10000  Related Section: N/A 
Applicable Control Mode: ALL   
Unit: pulse, Kpps, r/min 
Range: 0 ~ 30000   
Settings: 0: Disabled 
This parameter is used to set the value of gain switching condition (pulse error, Kpps, r/min) 
selected in P2-27. The setting value will be different depending on the different gain switching 
condition. 
 
P2 - 30■ 
 
INH  Auxiliary Function  Communication Addr.: 021EH
Default: 0  Related Section: N/A 
Applicable Control Mode: ALL 
Unit: N/A 
Range: 0 ~ 5   
Settings: 
0: Normal operation of Digital Inputs SON, CW, and CCW. 
1: Force the servo drive to be Servo On (ignore CW and CCW signal) 
2: Ignore CW digital input signal 
3: Ignore CCW digital input signal 
4: Internal position learning function 
5: After setting P2-30 to 5, the setting values of all parameters will lost (not remain in memory) at 
power-down. When the parameters data are no more needed, using this mode can allows users 
not to save parameters data into memory without damaging the EEPROM.  
NOTE
 
1)  Please set P2-30 to 0 during normal operation. When the communication control function is 
used, ensure that P2-30 is set to 5. The setting value of P2-30 will return to 0 automatically 
after re-power the servo drive.
