Parameter Function Explanation
MB_Brake
Mechanical brake
Contact closes after expiration of the magnetic
fl
ux creation
time. When the contact close, the mechanical brake must be
immediately opened via an external contactor.
/V<V_G1
inverted function of "V<V_G1
Contact closes when the limit value set in the "Control system"
menu V_G1 is exceeded.
/V<V_G2
Inverted function of
“
V<V_G2
”
Contact closes when the limit value set in the "Control system"
menu V_G2 is exceeded.
V=0
Speed = 0
Contact opens at start of travel, when actual speed > 0 m/s
Contact closes at the end of travel when actual speed = 0 m/s
and output for control mode contactor = 0
PFU
Recuperation unit Switching the feedback unit to standby function to save energy
Suspension
means
Suspension means replacement nec-
essary
Contact closes if the current suspension means can be used for
approx. 1 more year.
Contact stays close until the down-counter will be reset.
TD_CNT ext.
Monostable trigger circuit
The output relay gives an impulse to the output at every travel
direction change.
For connecting an external counter, e.g. in the control system
Full load
Full load
Contact closes when motor current is exceeded for 200 ms dur-
ing constant travel
SD
Speed monitoring
Closed Loop operation:
Output becomes active when deceler-
ation from V3 actual speed < limit value V_G1.
Open Loop operation:
Output becomes active when decelera-
tion from V3 nominal speed < limit value V_G1.
Output becomes inactive as soon as actual/nominal speed = 0
STO-Info
Status of the STO function
Contact is closed when the output stage is not blocked by the
STO function (output is only information, not safety-related).
/STO info
Inverted function of STO info
Contact is closed when the output stage is blocked by the STO
function (output is information only, not safety-related).
BR Info
Status of brake monitor inputs
BR1...BR4
The contact is closed when the brakes are open during travel
ZR_EN
ZArec: Enable of ZArec4C power feed-
back unit Contact closes when the following signals are present: controller
enable, travelling speed and direction speci
fi
cation.
Stutter br.
Stutter brake
Contact opens if the speed of the elevator cabin exceeds the
limit value con
fi
gured in the parameter V_G1.
Contact closes if the speed is below the limit value.
MotShorts
Signal for switching a motor short-cir-
cuit contactor If an external contactor is used to short-circuit the motor, this
signal can be used to switch it.
EvaDisMains
Signal for disconnecting the mains for
emergency evacuation via battery
If the system is switched to battery operation (see input function
48:EVA act.), this output signal disconnects the mains. As soon
as the system is at a standstill, the ZAdyn restarts and waits for
the line voltage to be restored.
