11.1.12 Zero return speed (Creep) [BFM #14027, #14026, BFM #14227, #14226]

This parameter sets the mechanical zero return operation speed (creep) [DOG, Stopper #1, #2].

*1. Refer to the section shown below for details on the user units and converted pulse data.
Note
• Set the zero return speed (creep) at or below the maximum speed and zero return speed (high speed).
When the zero return speed (creep) exceeds the maximum speed, 20SSC-H operates at the maximum
speed.
• Set the speed as slow as possible to achieve the best stop position accuracy.

11.1.13 Mechanical origin address [BFM #14029, #14028, BFM #14229, #14228]

This parameter sets the current value address at zero return operation completion.
After mechanical zero return completion, the 20SSC-H writes the current address to this parameter.

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,
Stopper #1].
The mechanical zero return ends at the specified number of zero-phase signal count.

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.
