Abstract

PURPOSE: To set the acceleration time until the command value to an optional value, by changing the limit voltage of a limit circuit in proportion to the command value.
CONSTITUTION: The command value ei is limited by the limit circuit consisting of the operational amplifiers 8 and 9 plus the diode 13 after an amplification through the operational amplifier 7 to be then supplied to an integrator. The output voltage eo of the integrator is fed back to the amplifier 7 to be compared with the command value ei. Here an equal value is selected for both the operation resistances 11 and 12, and the output voltage is controlled by the gain control resistance 14 for the amplifiers 8 and 9 to set the limit value eL to an optional value. The value eL is proportional to the value ei which means the input voltage of the amplifiers 8 and 9. The voltage value (e) increases with the time lapse after the application of the value ei, and the integrating action is stopped at eo=ei since a negative feedback is given to the value (e) by the amplifier. These times mean the acceleration time T, and the time T can be set to an optional value regardless of the command value.
