11.1.14 Zero-phase signal count [BFM #14030, BFM #14230]
This parameter sets the number of zero-phase signal counts in the mechanical zero return operation (DOG
type).
The mechanical zero return ends at the specified number of zero-phase signal count.
→
For details on the mechanical zero return, refer to Section 8.1
Note
• With the value "0" set in mechanical zero return operation [DOG], the 20SSC-H immediately stops when
the zero-phase signal count starts. In this case, the operation abruptly stops from the zero return speed
(creep/high speed). Observe the following items to protect peripheral devices from damage.
- Set the zero return speed (creep) as slow as possible for safety.
- Change the trigger of the zero-point signal count at the DOG backward end.
- Design the DOG to allow the machine to gently decelerate to the zero return speed (creep) before the
zero-phase signal count.
11.1.15 Zero return mode [BFM #14031, BFM #14231]
This parameter selects mechanical zero return operations.
→
For details on the zero return operation, refer to Section 8.1
11.1.16 Servo end evaluation time [BFM #14032, BFM #14232]
This parameter sets the evaluation time for the servo end check.
→
For details on the servo end check, refer to Subsection 7.9.2
Note
• To apply this function, set b0 in the operation parameter 2 to ON.
→
For details on the operation parameters 2, refer to Subsection 11.1.2
• For a servo end evaluation time setting outside of the range, see the following:
- Becomes 1 ms when set at 0 ms or less.
- Becomes 5000 ms when set at 5001 ms or more.
