M-Maxâ„¢ Series Adjustable Frequency Drive - Eaton Corporation

CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Any contactors and switching devices on the power side are
not to be opened during motor operation. Inching operation
using the power switch is not permitted.
Contactors and switching devices (repair and maintenance
switches) on the motor side must never be opened while the
motor is in operation when the frequency inverter is set to
speed control operating mode (P11.8 = 1).
Inching operation of the motor with contactors and switching
devices in the output of the frequency inverter is not
permitted.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Make sure that there is no danger in starting the motor.
Disconnect the driven machine if there is a danger in an
incorrect operational status.
WARNING
If a start signal is present, the drive is restarted
automatically, if P3.1 = 0 is set (REAF = Restart after
FAULT) and the error message has been acknowledged
(Reset).
WARNING
If a start command is present at a digital input (DI1–DI6)
assigned at P3.21, the sequence control also starts
automatically (without switch edge) when the power
supply is switched on (for example, after a power supply
failure).
CAUTION
A high torque at low speed causes a high thermal load on the
motor. If temperatures are too high, the motor should be
equipped with an external fan.

CAUTION
A high torque at low speed leads to a high thermal load on
the motor.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram. DC braking results in additional heating of the
motor. Configure the brake torque, set via braking current
(P12.1) and the braking duration (P12.2 and P12.4), as low as
possible.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
The motor parameters must be identical in both parameter
groups (P7 and P14).
CAUTION
Although the registers to be written are consecutive, the ID
numbers of the parameter list are not. Only the ID numbers
in the process data list are consecutive.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
The inching range is not permitted via the input contactor
(Pause time 60s between switching off and on).
CAUTION
The surface temperature of the resistors can reach values of
over 212°F (100°C).
