Page 37 The Hitachi inverter is a rugged and reliable device. The intention is for the inverter to assume the role of controlling power to the motor during all normal operations. Therefore, this manual instructs you not to switch OFF power to the inverter while the motor is running (unless it is an emergency stop).
Page 38 “Dynamic Braking” on page 5–6 for more information). For loads that continuously overhaul the motor for extended periods of time, the SJ700 may not be suitable (contact your Hitachi distributor). The inverter parameters include acceleration and deceleration, which you can set to match the needs of the application.
Page 39 1–17 SJ700 Inverter Acceleration and deceleration settings specify the time required to go from a stop to maximum frequency (or visa versa). The Maximum speed Speed resulting slope (speed change divided by time) is the acceleration or deceleration. An increase in output frequency uses the accel- eration slope, while a decrease uses the deceleration slope.
Page 40: Frequently Asked Questions
1–18 Frequently Asked Questions Frequently Asked Questions What is the main advantage in using an inverter to drive a motor, compared to alternative solutions? A. An inverter can vary the motor speed with very little energy loss, unlike mechanical or hydraulic speed control solutions. The resulting energy savings can often pay for the inverter in a relatively short time.
Page 41 How many poles should the motor have? A. Hitachi inverters can be configured to operate motors with 2, 4, 6, or 8 poles. The greater the number of poles, the slower the top motor speed will be, but it will have higher torque at the base speed.

Page 48: Step-By-Step Basic Installation
2–6 Step-by-Step Basic Installation Step-by-Step Basic Installation This section will guide you through the following basic steps of installation: 1. Study the warnings associated with mounting the inverter. 2. Transport or lift the inverter (and DC reactor, if used) in a safe manner. 3.
Page 49 2–7 SJ700 Inverter The position and orientation of the inverter are very important. Install the inverter vertically and securely with screws or bolts on a surface that is free from vibrations and that can bear the inverter’s weight. If the inverter is not installed vertically, its cooling performance may be degraded and trip events or inverter damage may result.
Page 50 2–8 Step-by-Step Basic Installation Step 2: To summarize the caution messages—you will need to find a solid, non-flammable, vertical surface that is in a relatively clean and dry environment. In order to ensure enough room for air circulation around the inverter to aid in cooling, maintain the specified clearance Ensure Adequate around the inverter specified in the diagram.

Operating Procedures WARNING: Be sure to turn ON the input power supply only after closing the front case. While the inverter is energized, be sure not to open the front case. Otherwise, there is the danger of electric shock.
Page 166: Optional Controlled Decel And Alarm At Power Loss
4–4 Optional Controlled Decel and Alarm at Power Loss Optional Controlled Decel and Alarm at Power Loss With the default SJ700 inverter configuration, a sudden power loss will cause the inverter to shut down immediately. If running at the time, the motor and load will coast to a stop. And without power, the inverter’s alarm output will not activate.
Page 167 4–5 SJ700 Inverter Follow the steps to implement the wiring change shown in the previous diagram. 1. Remove the 2-wire jumper J51 (terminals [R0] and [T0] to connector J51). 2. Procure several inches of multi-strand 20 AWG (0.5mm ) or slightly heavier wire. 3.
Page 168: Optional Controlled Decel And Alarm At Power Loss
4–6 Optional Controlled Decel and Alarm at Power Loss The timing diagram below shows a power loss scenario and the related parameter settings. During the controlled deceleration the inverter itself acts as a load to decelerate the motor. With either a high-inertia load or a short deceleration time (or both), it is possible that the inverter impedance will not be low enough to continue linear deceleration and avoid an over-voltage condition on the DC bus.
