Unable to set forward limit to the specified value because of Hard Motor Limit settings.
Hyperterm 6.4 code#
If the arguments to this command are valid, the controller responds to this command with an ASCII digit: Response Code If you try to set a temporary limit in a way prohibited by the corresponding hard limit, the temporary limit value is set to the hard limit and the response code byte indicates that the value could not be set as requested. This means that the Maximum Speed, Acceleration, and Deceleration temporary limits cannot be increased beyond their hard-limit counterparts and the Brake Duration limits cannot be decreased below their hard-limit counterparts. The hard limits configured through the Simple Motor Control Center are considered minimal safety requirements, and the temporary limits cannot be changed in a way that makes the controller “less safe” than this. Note that the Hard Motor Limit settings place restrictions on the limit values you can set with this command (see Section 5.2 for more information on the hard motor limits). Note: The Brake Duration units used by this command are 4 ms, which differs from 1 ms units used by the Brake Duration variables returned by the Get Variable command. The following table provides the limit IDs for all of the temporary motor limit variables along with the allowed limit values: ID Limit IDs from 4 to 7 affect only forward limits and limit IDs from 8 to 11 affect only reverse limits. Limit IDs from 0 to 3 are affect both forward and reverse limits equally (they are “symmetric”). This command lets you change the temporary motor limit variables documented in Section 6.4. This particular variable has units of 0.1 ☌, which would mean that the board temperature is 28.6 ☌. The rest of the characters before the carriage return () and new line () characters are an ASCII representation of a decimal (base 10) number. The leading ‘.’ is a status character that indicates the last command was understood and no errors are currently stopping the motors.
Hyperterm 6.4 serial#
If the argument variable_id is between 41 and 127, a Serial Format Error occurs.Įxample: The following commands both request the board temperature (variable ID 24, or 0x18): The value of the requested variable is transmitted as an ASCII-encoded decimal number. See Section 6.4 for a list of all of available variables. This command lets you read a variable from the Simple Motor Controller. Examples: The following commands all make the motor brake as hard as possible: If the argument brake_amount is outside the allowed range, a Serial Format Error occurs.Įrror. You can represent the brake amount in hex by putting an “H” at the end of the number. The argument brake_amount can be an integer from 0 (maximum coasting) to 32 (full braking) or an integer percentage from 0% to 100%. This command causes the motor to immediately brake by the specified amount (configured deceleration limits are ignored). It behaves the same as the Motor Forward command above, except the motor turns in the opposite direction. This command sets the motor target speed in the reverse direction. Motor Reverse (Serial/USB input mode only) If the argument speed is outside the allowed range, a Serial Format Error occurs.Įxamples: The following commands all make the motor drive forward at half speed: You can represent the speed in hex by putting an “H” at the end of the number.
Hyperterm 6.4 full#
The argument speed can be an integer from 0 (motor stopped) to 3200 (motor forward at full speed) or an integer percentage from 0% to 100%. This command sets the motor target speed in the forward direction. Motor Forward (Serial/USB input mode only) When Safe-Start protection is enabled, this command must be issued when the controller is first powered up, after any reset, and after any error stops the motor. This command clears the Serial/USB safe-start violation and allows the motor to run. Sending ASCII commands to the Simple Motor Controller from HyperTerminal (with echoing of typed characters enabled).Įxit Safe-Start (Serial/USB input mode only)
