Chapter 7 Servo Parameters|ASDA-AB Series
7-76
Revision January 2009
Bit5: Reserved. Must be set to 0.
Bit6
Bit6: Abnormal pulse command detection
0: enable abnormal pulse command detection
1: disable abnormal pulse command detection,
If the detection function is disabled, the ALE08 will not come out when the pulse frequency is
higher than 570Kpps.
Bit7 ~ Bit9: Reserved. Must be set to 0.
Bit10
Bit10: DI ZCLAMP function selection
0: Locked at the position when ZCLAMP conditions are satisfied.
1: Speed command is forced to 0 r/min when ZCLAMP conditions are satisfied.
How to select these two functions?
If the users want to use the edge of a D1 signal to stop the motor at the desired position and do
not care the speed deceleration curve, then set Bit10 of P2-65 to 0.
If the users want to eliminate the analog voltage offset to stop the motor at low voltage and they
want to keep the acceleration and deceleration speed curve, then set Bit10 of P2-65 to 1.
When the following conditions are all met, ZCLAMP function will be activated.
Condition1: Speed mode
Condition2: DI ZCLAMP is activated.
Condition3: External analog speed command or internal registers speed command is less than
parameter P1-38.
Bit11 ~ Bit15: Reserved. Must be set to 0.
