APPENDIX F: SPEEDSYS300 ODS301 MODBUS REGISTER DEFINITIONS
F.1.2 Control
Table F-2 describes the SpeedSys300 ODS301 Modbus registers related to
control parameters.
NOTE: The Modbus registers in this data block are read only.

Address Name
Data
type
Range Access Description
0100 access_pass char16 Level 0
Writing this register controls the access level
to the module.
Read/write for each access level.
Writing string equal to parameter
“admin pass” grants admin-level access
(see also Modbus register 1000
(admin_pass)).
Writing factory password grants factory-level
access (if factory access jumper is closed).
Writing other value sets user-level access.
0108 prog_mode uint16 Level 0
Programming mode setting command.
Read/write for each access level.
Code 0x33 – Enter parameter programming
mode.
Code 0x55 – Restore admin default.
Code 0x66 – Save current as default.
Code 0x77 – Restore current settings.
Code 0xAA – Save settings.
0109 PWM_output uint16 Level 2
Current value of PWM-setting for analog
output.
Read/write for factory-level access.
Used for factory output calibration.
0110 output_disable uint16 Level 2
Disable updating “Pwm output” by output
routine.
Read/write for factory-level access.
Setting value 1 in this object disables output
control routine to update analog output.
It makes possible to use “PWM output”
object for analog output calibration.
0111 diag_cmd uint16 Level 0
Diagnostic command.
Read/write for each access level.
Writing 1 to:
B0 – Resets min/max values of “min rpm”
and “max rpm”, “min acc” and “max acc”.
B1 – Resets system error memory
B2 – Resets loop exec times
B3 – Reset slave error memory
B4 – Reset event log (factory-level access
required).
0112 proof_req uint16 Level 0
B0 - Simulate digital input “Proof test”.
Read/write for each access level.
