A maximum interpolation period, in ms (milliseconds), can be configured for the TTL
interface using P601[0] - ENC_CH1_Period. Within this context, Period is the
maximum time of “no activity” since the last TTL counter event:
 Period=0:Functiondisabled(default)
 Period>0(=nms):Ifnocountereventisregisteredinnms,thespeedwill
besetto0.
Zero pulse
There is no parameter for activating the zero pulse evaluation here, as this
evaluation is controlled exclusively based on the homing mode (see Section
"Homing" on page 189). However, setting P541[0] - ENC_CH1_NpTest to1
provides a test mode that can be used during commissioning in order to be able to
activate the zero pulse evaluation even without homing. Scope signals 1014 and
1016 can be used to view a received zero pulse within this context. This test mode
must be disabled during normal operation (P541[0] = 0).
Commutation
Motor operation with pure incremental encoders needs for the auto commutation
function to be enabled without fail. For details see Section "Synchronous motor
auto commutation" on page 144.
