4-Q speed
controller
The motor produces positive torque in the selected or programmed direction. When the speed set value
is reduced or the direction changed (direction preselection version) the load is actively decelerated as to
the factory-set speed ramp.A load can be permanently decelerated.
Remark
When the load is decelerated, energy is fed back to the operating voltage supply. Thereby, the operating
voltage can undesirably increase and can damage in parallel connected consumers. Use an operating
voltage supply with feed-in possibility or a brake choppers to prevent excessive voltage surges.
Brake chopper Limits the operating voltage to a preset value as soon as its feed-in should rise above the threshold
value.
Direction
CW/CCW
As seen towards the mounting flange:
• CW = shaft turns to the right (clockwise)
• CCW = shaft turns to the left (counterclockwise)
IP40 Protected against access to dangerous parts with a wire, tool, or similar ≥Ø 1 mm and against solid for-
eign bodies ≥Ø 1 mm. No protection against water.
Max. torque
M
max
[mNm]
The maximum torque the motor can produce for a short term. It is limited by the overload protection of
the electronics.
Max. current
I
max
[A]
Supply current with which the peak torque is generated at nominal voltage. With an active speed con-
troller, the supply current is not proportional to the torque, but also depends on the supply voltage. As a
result, this value only applies at nominal voltage.
