4.3.10. Read / write parameter JOG step number, command „l“ (6Ch)
This command is to read or write the step number relating to the jog function within the value range 0- 999.
Parameter 0 will disable the Jog function, both by keypad and by external inputs.
Note: The jog function must be enabled in command „m“, lock in one direction possible as an option.
The respective step is always completely accomplished and during the motor positioning operation cannot be
stopped or restarted by actuating another key. However, stop by interface (command „D“) is possible. With
running motor the moving bit is set to 1 (refer also command “F”).
Example 1: Read jog step number
SOH Adr Cmd SCmd EOT CRC
Transmission
01h 20h 6C 53h 04h 5Ah
SOH Adr Cmd SCmd Step number = 25 EOT CRC
Response
01h 20h 6Ch 53h 30h 30 32 35 04h 44h
Example 2: Write jog step number
SOH Adr Cmd SCmd Step number = 50 EOT CRC
Transmission
01h 20h 6Ch 53h 30h 30 35 30 04h 52h
SOH Adr Cmd SCmd Step number = 50 EOT CRC
Response
01h 20h 6Ch 53h 30h 30 35 30 04h 52h
Example 3: Value transmitted too high (4 digits)
SOH Adr Cmd SCmd Step number = 2345 EOT CRC
Transmission
01h 20h 6Ch 53h 32h 33 34 35 04h 64h
SOH Adr Cmd SCmd Step number = 0345 EOT CRC
Response
01h 20h 6Ch 53h 30h 33 34 35 04h 44h
SPA accepts only 3-digit values, the 4th digit is automatically replaced by zero.
4.3.11. Read and write specific parameter „x“ (78h)
The specific parameter „x“ comprises several sub-parameters enabling alteration of originally permanent
parameters to adapt them to new circumstances. At present, the following sub-parameter is available:
D (44h) = minimized delaytime of serial interface
L (4Ch) = hide LCD digit
Sub parameter: Delaytime „D“ (44h)
This parameter defines the minimum delay time (timeout) between the last bit received and the first bit of the
response transmitted. Delay time is in steps of 0,1 ms within the range from 00.0 ... 60,0 ms. Default is 1,0 ms.
Example 1: Read current delaytime
SOH Adr Cmd Sub EOT CRC
Transmission
01h 20h 78h 44h 04h 7Ch
SOH Adr Cmd Sub Delaytime = 4.5 EOT CRC
Response
01h 20h 78h 44h 30h 30h 34h 35h 04h BBh
Example 2: Write new delaytime
SOH Adr Cmd Sub Delaytime = 15.0 EOT CRC
Transmission
01h 20h 78h 44h 30h 31h 35h 30h 04h BDh
SOH Adr Cmd Sub Delaytime = 15.0 EOT CRC
Response
01h 20h 78h 44h 30h 31h 35h 30h 04h BDh
Please not that the true delaytime might be extended. It depends on the required processing time as well as on
internal software cycles. The tolerance is approx. 8 ms.
