5. Electrical Connection
Carry out any work on live equipment in compliance with the national safety and accident prevention regula-
tions. Carry out electrical installation in compliance with the relevant regulations. In particular, follow the
installation instructions ensuring electromagnetic compatibility (EMC), e.g. shielding, grounding, filter
arrangement and laying of cables. This also applies to equipment with the CE mark. It is the responsibility of
the manufacturer of the system or machine to ensure conformity with EMC limits.
Contact your supplier or Omron-Yaskawa Motion Control representative when using leakage current circuit
breaker in conjunction with frequency inverters.
In certain systems it may be necessary to use additional monitoring and safety devices in compliance with the
relevant safety and accident prevention regulations. The frequency inverter hardware must not be modified.
If Permanent Magnet Motors are used:
If a PM motor is turned by any external force, high voltage is generated in the windings.
•
During wiring, maintenance or inspection make sure, that the motor is stopped and can not turn.
•
If the inverter is turned off and the motor must be turned, make sure that motor and inverter output are
electrically disconnected.
6. Inverter Setup
This L7 inverter can drive induction motors as well as permanent magnet motors.
Always select the appropriate control mode:
•
For induction motors use V/f, Open Loop Vector or Closed Loop Vector control (A1-01 = 0, 2 or 3).
•
For permanent magnet motors use no other control mode than Closed Loop Vector for PM (A1-01 = 6).
A wrong control mode selection can damage the inverter and motor.
If a motor is exchanged or operated the first time, always set up the motor control relevant parameters using
the nameplate data or perform autotuning. Do not change the parameters recklessly. To ensure a safe operation
with PM motors always set the:
•
correct motor data
•
the PG open detection parameters
•
the speed deviation detection parameters
•
the over acceleration detection parameters
Wrong parameter settings can cause dangerous behavior or motor and inverter damage.
Refer to
page 12, Start Up Procedure
for details about the correct start up procedure.
7. Notes
The Varispeed L7 frequency inverters are certified to CE, UL, and c-UL.

1. Introduction
This manual was compiled to help system manufacturers using Omron-Yaskawa Motion Control frequency
inverters to design and install electrical switch gear. It also describes the measures necessary to comply with
the EMC Directive. The manual's installation and wiring instructions must therefore be followed.
Our products are tested by authorized bodies using the standards listed below.
