Chapter 7 Servo Parameters|ASDA-A&A+ Series
Bit5: Reserved. Must be set to 0.
Bit6
Bit6: Abnormal pulse command detection
Bit7 ~ Bit9: Reserved. Must be set to 0.
Bit10
Bit10: DI ZCLAMP function selection
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: Reserved. Must be set to 0.
B13
Bit 12: Undervoltage (Servo Drive Fault) clear mode selection
Bit 13: CWL/CCWL pulse input inhibit function
Bit14 ~ Bit15: Reserved. Must be set to 0.

0: enable abnormal pulse command detection
1: disable abnormal pulse command detection,
0: Locked at the position when ZCLAMP conditions are satisfied.
1: Speed command is forced to 0 r/min when ZCLAMP conditions are satisfied.
B12
0: When the main circuit voltage is within its specified limit or after Servo Off (the servo
drive is disabled), the fault, Undervoltage will be cleared automatically.
1: When turning ARST (DI signal) to be ON and the main circuit voltage is within its
specified limit also, the fault, Undervoltage will be cleared.
0: Disable CWL/CCWL pulse input inhibit function. In Pt mode, no matter CWL or CCWL
exists or not, external position pulse command will be input into the servo drive.
1: Enable CWL/CCWL pulse input inhibit function. In Pt mode, if CWL exists, the external
CWL pulse input into the servo drive will be inhibited and CCWL pulse input will be
accepted. On the one hand, in Pt mode, if CCWL exists, , the external CCWL pulse
input into the servo drive will be inhibited and CCWL pulse input will be accepted.
Please note that if CWL and CCWL both exist, CWL and CCWL pulse input into the
servo drive will be both inhibited.
