Terminals and relay functions
S X111: READY RELAY:
– terminals 72 – 73.1: NO contact in the quiescent state
– terminals 73.2 – 74: NC contact in the quiescent state
For S1.2=OFF, the relay switches if the following conditions are fulfilled:
– internal main contactor CLOSED (terminals NS1–NS2 connected, terminal 48 enabled)
– terminals 63, 64 =ENERGIZED
– no fault present (also not on feed drive 611A Standard,
or 611D drives)
– feed drive with Standard interface or resolver is enabled for the ”ready” setting (terminals
663, 65)
For S1.2=ON, the relay switches if the following conditions are fulfilled:
– internal main contactor CLOSED (terminal NS1–NS2 connected, terminal 48 enabled)
– no fault present (also not on feed drive 611A Standard, and 611D drives)
– feed drive with Standard interface or resolver enabled for this ”ready” setting
(terminals 663, 65).

t_alarm and motor overtemperature:
terminal 5.1 – 5.2: NO contact in the quiescent state
terminal 5.1 – 5.3: NC contact in the quiescent state
This relay switches, if:
– the > heatsink temperature monitoring responds at the I/R
– the > motor temperature monitoring responds at the 611D feed drive
> heatsink temperature monitoring responds
– at the feed drive 611A user–friendly

S X171: Terminal NS1–NS2 (coil circuit of the internal line supply– and pre–charging contac-
tor):
– is used to electrically isolate from the line supply
(signal contact, terminals 111–213 must be interrogated)
– may only be switched if terminal 48 is open–circuit (without any restriction from
Order No. 6SN114V–1VV01–0VVV for 10, 16 and 55kW, from
Order No. 6SN114V–1VV02–0VVV for 36kW, all 80 and 120kW)

S terminal 63: Pulse enable
– has the highest priority for pulse enable of all the modules
– acts instantaneously (without delay)
S Terminal 64: Drive enable
– acts instantaneously on all modules
– when the signal is withdrawn, n

is set to 0 for all drives, and
> for main spindle drive / induction motor module 611 A, the pulses are canceled
after a speed, which can be set, is fallen below. The drive is braked
along the ramp.
