Hitachi SJ300 Series Manuals

Hitachi America, Ltd. EN-021302-1 ENGINEERING NOTE SUBJECT: Parameter A85, Operation Mode Selection AFFECTED MODELS: L300P and SJ300 The manuals for the SJ300 and L300P show three settings for Parameter A85. This is ONLY correct for the SJ300. There are only TWO settings for the L300P: “00” for Normal Operation, and “01” for Energy-Saving Operation. The latter setting seeks to adjust the output voltage at any given output frequency to minimize the motor current, and hence power consumption at that speed. This function only acts at constant speed – not during acceleration or deceleration. Optimal Accel/Decel Operation (SJ300 ONLY) In addition to “Normal” and “Energy Saving” modes, the SJ300 offers a third setting option, “02” for Optimal Accel/Decel Operation. This function is an implementation of a “fuzzy logic” algorithm. In real time, the function automatically adjusts the acceleration and deceleration times in response to changes in load or inertia, to take advantage of the maximum output current capability of the inverter. In general, this mode will allow for the shortest accel and decel times based on the actual load conditions. The function continuously monitors output current and DC bus voltage to ensure that their respective trip levels are not reached. In this mode, the settings of acceleration and deceleration times (F002 and F003) are disregarded. The acceleration time is controlled to maintain output current below the level set by the Overload Restriction Function if enabled (Parameters B21/B24, B22/B25, and B23/B26). If Overload Restriction is not enabled, then the current limit used is 150% of the inverter’s rated output current. The deceleration time is controlled so that the output current is maintained below 150% of the inverters rated current, AND the DC bus voltage is maintained below the OV Trip level (358V or 770V).

PGC - 10/23/01 Page 1 of 1 Hitachi America, Ltd. EN-102301-1 ENGINEERING NOTE SUBJECT: CAUTIONS!! ANALOG INPUT FUNCTION AFFECTED MODELS: ALL SJ300 AND L300P If the value of parameter A001 (Frequency Source Selection) is set to “01” (terminal) - AND - the AT function (data=16) is NOT assigned to any of the intelligent input terminals, the function of the “O2” analog input terminal will be as described in the table below: Value of Parameter A006 (O2 Selection) Action of Analog Inputs 00 ( Independent) Only the signal at the O2 terminal will reflected. Terminals O and OI will be disabled. When the signal at O2 becomes negative, the speed reference becomes negative, resulting in REVERSE direction of rotation. The action is the same when the multispeed terminal(s) and/or the jog terminals are ON. 01 (Only Positive) The speed reference will be the SUM of O+OI+O2. When the sum is negative, speed will be ZERO. 02 (Both Positive and Negative The speed reference will be the SUM of O+OI+O2. When the sum is negative, the speed reference becomes negative, resulting in REVERSE direction of rotation. The action is the same when the multispeed terminal(s) and/or the jog terminals are ON Summary: In the case where the AT function is not assigned to any input terminal, and REVERSE rotation is not desired or unsafe, make sure that A006 is set to a value of “01”.
