The motor blower is protected internally when mounted in the RAC 2.2
by means of the Q1 circuit breaker.
The Q1 circuit breaker must be set as follows for axial blowers on 2AD
motors:
RAC 2.2 with 2AD 132/2AD 160 – 0.63 A
RAC 2.2 with 2AD 180 – 1.00 A
The value actually set depends on the respective supply module of the
RAC 2.2. Blowers of separate motors must be directly connected to
three-phase mains via a separate circuit breaker!
Pressing the "up" arrow key brings the motor speed N into the display.
Positive speed must be indicated on the display when the motor shaft is
rotated clockwise by hand (motor shaft viewed from front).
Press the "up" arrow until speed command value C appears.
• Positive voltage at connector X4/1 with respect to X4/2 shows a
positive command value in the display.
• For C-axis operation, apply positive command to connector X4/5 with
respect to X4/6. Activate command value input via EXT POS input and
parameter PQ-FUNCT (PQRS 16). A positive command value again
appears in the display (see section 3.8, "C-axis Operation").
The null of the command value input is set at the factory with
the inputs short-circuited and may be adjusted for command
value input X4/1 and X4/2 with potentiometer P1 to the left of
connector X4, and command value input X4/5and X4/6 with
potentiometer P2 to the right of X4.
Condition: separate spindle feedback must be connected to the optional
interface for the second encoder input (X5).
Press the "up" arrow key until spindle speed S appears on the display.
A positive speed must appear in the display when the incremental
encoder shaft is rotated clockwise by hand.
Press the "up" arrow key until motor temperature T appears.
• Indication with cold motor: „T<40°C“
• A flashing display means that the motor temperature sensors are
incorrectly connected or the motor temperature is less than 0°C.
• The drive switches off after ten minutes if the motor temperature
sensors are faulty. „NO TEMP“ appears. „TEMP WARN“goes to zero
30 seconds before this.
