Note:
• Do not do Deceleration Rate Tuning if you use a braking resistor unit or a regenerative converter.
• Do Deceleration Rate Tuning and KEB Tuning with the load attached to the motor.
• Do not do Deceleration Rate Tuning or KEB Tuning for these applications:
In Deceleration Rate Tuning and KEB Tuning, the drive will automatically rotate the motor forward and accelerate and decelerate the
motor again and again.
–On a machine that does not let the motor rotate forward
–In applications with a small range of operation (trolleys and other such applications that can only move linearly)
–In elevator applications
–Applications where sudden acceleration and sudden deceleration are not applicable.
• To do KEB Tuning with the external main circuit capacitors connected to the drive, set L3-26 [Additional DC Bus Capacitors] then do
KEB Tuning.
• Do not do KEB Tuning or Deceleration Rate Tuning if the drive is set to use H1-xx = 16 [MFDI Function Select = Motor 2 Selection].
Failure to obey can cause an ov [Overvoltage] fault.
