6.3 Reversing
Reversing is obtained by changing the armature polarity. The motor is
electrodynamically braked to standstill. The braking time must be set at the
timer relay such that the motor is safely at standstill before the armature is
reversed (for dimensioning of the brake resistor see chapter 6.2
"Electrodynamic braking").
To limit the switching voltage peaks, a zinc oxide varistor (R
U
) must be
connected in parallel to the controller output.
For long motor cables (> 50 m) or motors which are connected in parallel, it
may be necessary to use an interference suppression module (see chapter 3
"Accessories")
Reversing circuit:
1)
Interference suppression module
2)
Mains choke is only required for type 534
