Page 8: Warnings
Cables must not be connected or disconnected, nor signal tests carried out, while the power is switched on. The Varispeed E7 DC bus capacitor remains charged even after the power has been switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out maintenance.
Page 9: Safety Precautions And Instructions For Use
The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power. It is therefore necessary to wait for this time before opening its covers. All of the main circuit terminals may still carry dangerous voltages.

Page 164: Using Multi-Step Speed Operation
Frequency Reference Using Multi-Step Speed Operation With Varispeed E7 series Inverters the speed can be changed in a maximum of 5 steps, using 4 multi-step fre- quency references and one jog frequency reference. The following example of a multi-function input terminal function shows a 5-step operation using multi-step references 1 and 2 and jog frequency selection functions.
Page 165 The multifunction input setting “Jog Frequency 2” (69) can be used for jog frequency selection when a 3-wire control is used for the control circuit. If it is selected while the inverter is initialized to 2-wire con- trol an OPE03 alarm will be displayed.

Page 169 Deceleration to Stop If the stop command is input (the run command is turned OFF) when b1-03 is set to 0, the motor decelerates to stop according to the deceleration time that has been set. (Factory setting: C1-02 (Deceleration Time 1)).
Page 170: Using The Dc Injection Brake
Coast to Stop with Timer If the stop command is input (i.e., the run command is turned OFF) when b1-03 is set to 3, the Inverter output is switched off so that the motor coasts to stop. After the stop command is input, run commands are ignored until the time T has elapsed.
Page 171: Using An Emergency Stop
Set a multi-function input terminal (H1-01 to H1-05) to 15 or 17 (emergency stop) to decelerate to stop using the deceleration time set in C1-09. If inputting the emergency stop with an NO contact, use setting 15, and if inputting the emergency stop with an NC contact, use setting 17.

Page 174: Preventing The Motor From Stalling During Acceleration (Stall Prevention During Acceleration Function)
When L3-02 is exceeded, the acceleration will stop. If L3-01 is set to 2 (optimum adjustment), the motor accelerates so that the current is held at a level of 50 % of the inverter rated current. With this setting, the acceleration time setting is ignored.

Page 180: Jump Frequency Function (Operation Avoiding Resonance)
This function allows the prohibition or “jumping” of certain frequencies within the Inverter’s output fre- • quency range so that the motor can operate without resonant oscillations caused by some machine systems. It can also be used for deadband control.
Page 181: Speed Limit
There are two methods of limiting the minimum frequency, as follows: • Adjust the minimum level for all frequencies. Adjust the minimum level for the master speed frequency (i.e., the lower levels of the jog frequency, multi- • step speed frequency, and auxiliary frequency will not be adjusted).
Page 182: Frequency Detection
Speed Agreement Function There are four different types of frequency detection methods available. The digital multifunction outputs M1 to M4 can be programmed for this function and can be used to indicate a frequency detection or agreement to any external equipment.

Page 184: Improved Operating Performance
The torque compensation function detects a rising motor load, and increases the output torque. The inverter calculates the motor primary loss voltage and adjusts the output voltage (V) to compensate insuf- ficient torque at startup and during low-speed operation. The compensation voltage is calculated as follows: Motor primary voltage loss ×...

Set whether to enable or disable the stall prevention using parameter L3-05. Set the according deceleration times using C1-02 (Deceleration time 1) or C1-04 (Deceleration Time 2). If the Inverter output current reaches the set value in L3-06 – 2%, the motor will accelerate again to the set fre- quency.
Page 187: Load Detection
Load Detection If an excessive load is applied to the machinery (overload) or the load suddenly drops (loss of load), an alarm signal can be output via one of the output terminal M1-M2 or M3-M4. To use the load detection function, set B or 17 (overload/loss of load detection NO/NC) in one of the parame- ter H2-01 and H2-02 (terminals M1-M2 and M3-M4 function selection).

Page 193 Because this function uses a voltage signal to terminal A2, pin 2 of the DIP-switch S1 on the control terminal board has to be turned to OFF for A2 voltage input. The factory setting is ON (A2 current input). Refer to Chapter 2, Switch S1 - Standard Terminal Board.
Page 194: Limiting Motor Rotation Direction And Output Phase Rotation
(e.g., fans, pumps, etc.) It is also possible to change the output phase order by changing b1-04 to 2 or 3. This much easier and faster than changing the wiring if the motor rotational direction is wrong.
Page 195: Automatic Restart
To restart the Inverter after power is recovered, set L2-01 to 1 or 2. If L2-01 is set to 1, the inverter will restart, when power is recovered within the time set in L2-02. If the power loss time exceeds the time set in L2-02, an UV1 fault (DC bus undervoltage) will be detected.

Page 207: Ol2 Characteristics At Low Speed
OL2 Characteristics at Low Speed At output frequencies below 6 Hz the overload capability of the inverter is lower than at higher speeds, i.e. an OL2 fault (inverter overload) may occur even if the current is below the normal OL2 current level (see 6.41).

Page 212: Raising And Lowering Frequency References Using Digital Input Signals (Up/Down)
The UP and DOWN commands raise and lower Inverter frequency references by turning ON and OFF a multi- function digital input terminal S3 to S7. To use this function, set two of the parameters H1-01 to H1-05 (digital input terminal S3 to S7 function selec- tion) to 10 (UP command) and 11 (DOWN command).
Page 213 When d4-01 (Frequency Reference Hold Function Selection) is set to 1, the last frequency reference value is stored even after the power supply is turned OFF. When the power supply is turned ON and the run com- mand is input, the motor accelerates to the frequency reference that has been stored. To reset (i.e., to 0 Hz) the stored frequency reference, turn ON the UP or DOWN command before the power is switched on.
