1. In the MBC25P22 a sine cosine output function is used in rotating the motor The output current for a given motor is determined by the motors current rating and the wiring configuration of the motor There is a current adjustment potentiometer used to set the output current of the MBC25P22 This sets the peak output current of the sine cosine waves The specified motor current which is the unipolar value is multiplied by a factor of 1 0 1 4 or 2 0 depending on the motor configuration series half coil or parallel Step Motor Configurations Step motors can be configured as 4 6 or 8 leads Each configuration requires different currents Refer to the lead configurations and the procedures to determine their output current WARNING Step motors will run hot even when configured correctly Damage may occur to the motor if a higher than specified current is used Most specified motor currents are maximum values Care should be taken to not exceed these ratings 6 Lead Motors When configuring a 6 lead motor in a half coil configuration connected from one end of the coil to the center tap multiply the specified per phase or unipolar current rating by 1 4 to determine the current setting potentiometer value This configuration will provide more torque at higher speeds when compared to the series configuration P4 P2 P3 P4 When configuring the motor in a series configuration connected from end to end with the center tap floating use t2. generator Check to see if the parameters are invalid for the command that was sent A bad command was sent to the pulse generator Please check to Command Error see that the command being sent is valid or that the pulse generator is not running To many parameters sent back to the PC This is an internal error Transmitt Error caused by the eeprom Motor speed profiles are set incorrectly Please make sure that the 16 Motor Error base speed is less than the max speed and that the speeds are within their valid ranges There were no parameters sent to the pulse generator A command was sent to the pulse generator that expected to see parameters after the command Zero Parameters Error ASCII Table for Direct Mode ASCII Hex ASCII Hex ASCII Hex Symbol Value Symbol Value Symbol Value L010142 22 October 2003 Torque Speed Curves MBC25P22 with 23L104 2 0A 24V Div By 8 S
