5) Set positive/negative value limit, stop motion mode, and whether software limit is
enabled
Figure 3.71
N-Limit item: Value of negative limit. API function's argument variable “NLimit”.
P-Limit item: Value of positive limit. API function's argument variable “PLimit”.
Stop mode pull-down menu: Stop mode. API function's argument variable
“action”.
Soft-limit Checkbox: Enables/disables software limit.
6) If software limit is enabled, you must check the “Soft-limit Enable” checkbox and
execute the following procedure:
/* Start software limit configuration */
rt = _DMC_01_enable_soft_limit(gDMCCardNo, NodeID, SlotID, action);
// action argument specifies the stop mode to use when limit is reached. A value of 1
means an emergency stop; A value of 2 means a slow down stop.
/* Set the values for positive and negatives */
rt = _DMC_01_set_soft_limit(gDMCCardNo, NodeID, SlotID, PLimit, NLimit);
// PLimit argument is the set value for positive limit; NLimit is the set value for
negative limit
7) To disable software limit, you must use the following procedure:
rt = _DMC_01_disable_soft_limit(gDMCCardNo, NodeID, SlotID);
8) Set Servo Motor Power ON/OFF(servo on/servo off)
Figure 3.72
Click on the “SVON” button to execute the following procedure:
rt = _DMC_01_ipo_set_svon(gDMCCardNo, NodeID, SlotID , ON_OFF);
// ON_OFF: 0 – Servo Power OFF; 1 – Servo Power ON
