Description
3.3 Motor series that are supported
There are a few constraints on operation:
Table 3- 6 Constraints on operations using encoderless synchronous motors
Revision level of inverter
• Revision level of power module ≥ B01
• Firmware version of the Control Unit: ≥ FW V4.7
Applications Suitable for applications using stationary operation in the range of the
rated speed of the motor :
• Conveyor belts
• Roller conveyors
• Chain conveyors
Speed of the motor
• Speed ≤ rated speed of the motor
Operation is not permitted in field weakening.
• In stationary operation ≥ 15 % of the rated speed.
For accelerating and reversing functions, speeds 0 … 15 % of the
rated speed are permitted.
Switching on when motor
The "flying restart" function is not possible.
Only "STO" is permitted by the safety functions integrated in the drive.
Ambient temperature of
motor
≤ 40 °C
The inverter monitors the motor through a temperature model. The tem-
perature model presumes an ambient temperature of 40°C.
In the case of higher ambient temperatures, the inverter will no longer be
able to provide sufficient protection for the motor. If you operate the
motor in ambient temperatures > 40 °C, you must reduce the power of
the motor sufficiently.
Information on temperature-dependent power de-rating can be found in
