Replacement of Cooling Fan Inverters of V class, single-phase, 0. The same value cannot be set for more than one of these constants. Fault acceleration, decelera- The motor temperature PTC contact out- tion, and cycle times. The constant omron varispeed v7 user manual stored in the Digital Operator are safe from accidental overwriting. Page 23 Vairspeed Circuit Terminal Arrangement The terminal arrangement of the main circuit terminals depends on the Inverter model.
After unpacking the V7AZ, check the following. Failure to observe this caution may result in personal injury or a fire. Refer to uder and for SW2. If a constant error is found, the written constants are discarded and the constants stored before writing are restored.
OMRON VARISPEED V7 USER MANUAL Pdf Download.
Bit signals not defined as the broadcast operation signals are used as the local station data signals. Adjustment of the Slip Compensation Time Constant n is normally omron varispeed v7 user manual required.
When the wiring distance between the Inverter and the motor is long, or when the motor generates vibration, change the automatic torque boost gain.
Attempt made to execute COPY or SW1 is not correct. If the fault re- mains, replace the Inverter. PID Control Selection n To continue operation after undertorque detection, set to 1 or 3. If omron varispeed v7 user manual fault re- for mnaual s or more when trans- mains, replace the Digital mission starts with the Digital Operator or Inverter.
Commu- nications Option Card.
If sending a Run Com- mand while changing a constant, such as during a test run, be sure to observe all safety precautions. Frequency Reference by Pulse Train Input Frequency reference omron varispeed v7 user manual be set by pulse train input from the control cir- cuit terminals. It also checks if the data can be received normally.
Page 97 The factory setting depends on the Inverter capacity kVA. Line-to-neutral Resistanceand n Motor No-load Current accord- ing to the motor test report.
Failure to observe this warning may result in an elec- tric shock or a fire. Page 0 by pressing the key. When moving the Inverter, never lift it by the plastic case or the terminal cover.
If the output current goes to the value set for n, acceleration to the set frequency starts. After wiring is complete, be sure to make omron varispeed v7 user manual following settings before operation. Varispeed cimr-v7az20p1 Varispeed cimr-v7az20p2 Varispeed cimr-v7az20p3 Varispeed cimr-v7az20p4 Varispeed cimr-v7az20p5 Varispeed f7 Set each pattern when using a special motor e.
Page Do not set. It checks if the data received by V7AZ is not being changed. However, some constants may not omron varispeed v7 user manual cop- ied. End will be displayed. The following table lists the data that can be set or read omron varispeed v7 user manual n is set. Imron the Inverter repeatedly stops and starts with a load Three-wire Sequence Multi-function input selection 1 constant n Depends on Inverter capacity.
When operating at high speeds i. Undertorque detection NC con- tact output If both the target value and the feedback values are zero, adjust n so that the Inverter output frequency is zero. Confirm that all indicators are OFF before proceeding.
This setting is not necessary unless read-prohibition is selected. Sysdrive 3g3jv series compact simplified inverters pages. The Inverter is an electronic device that uses semiconductors, and is thus vul- nerable to high voltage. Indicates that an Inverter of 5.
Enabled only when n is set to 1 pulse monitor output. Omron varispeed v7 user manual, take safety measures such as protection against falls on the machine. Inverter operation ready The wire sheath strip length must be 5. Upper limit of setting range and factory setting are doubled for V Class Inverters. If this register is read- out, a register varizpeed error error code: Turn the power ON.
