Commissioning
5-3
48XX/49XXSHB0399
The following table describes briefly how to commission a DC shunt motor with an
attached tacho according to the example in FIG 5-1(see chapter 15).

Switch-on sequence 1.X2/28 (Ctrl. enable) must be opened (LOW)
2.Connect the mains
Approx. 0.5sec after mains connection the
controller is ready for operation.
The time t
1
depends on the initial response
of the field current
Typical values: t
1
= 300ms ...600ms
t
2
= t
1
+ 20ms

Setpoint selection 8.Apply a voltage higher than 0V (max. 10V)
- do not achivate JOG setpoint (LOW signal at X2/E4 and X2/E5)
Check whether LED
’RDY’ ison 9.If RDY is off and C067 is blinking, remove TRIP first. Chapter 8.1 ff.
Controller enable 10. Assign HIGH-signal to X2/28 (+ 13...+ 30 V) and do not press STP
The motor will now run with the selected setpoint and in the selected direction of rotation. If
necessary, adapt the controller to your application. Chapter 5.3
Additional settings 11. Further setting required for LECOM operation
Stop!
( Do not change the switch-off sequence
The controller must only be disconnected from the mains when it is inhibited or the
motor is in standstill (for mains switch-off logic see chapter 15.9.2).
