5-40 Function Relay
Array (Relay 1 [0], Relay 2 [1])
Select options to
dene
the function of the relays.
The selection of each mechanical relay is realized in an array
parameter. When parameter 0-03 Regional Settings is set to [0]
International, the default value is [9] Alarm; When
parameter 0-03 Regional Settings is set to [1] North America, the
default value is [160] No alarm.
Option: Function:
[193] Sleep Mode The frequency converter/system has
turned into sleep mode. See parameter
group 22-4* Sleep Mode.
[194] Broken Belt
Function
A broken-belt condition has been
detected. Enable the function in
parameter 22-60 Broken Belt Function.
[196] Fire Mode The frequency converter is operating in
re mode. See parameter group 24-0* Fire
Mode.
[198] Drive Bypass To be used as a signal for activating an
external electromechanical bypass,
switching the motor directly on line.
See parameter group 24-1* Drive Bypass.
5-41 On Delay, Relay
Array [2]
Range: Function:
0.01 s * [0.01 -
600 s]
Enter the delay of the relay cut in time.
Select 1 of 2 internal mechanical relays in an
array function. See parameter 5-40 Function
Relay for details.
Illustration 3.7 On Delay, Relay
5-42 O Delay, Relay
Array[2]
Range: Function:
0.01 s * [0.01 -
600 s]
Enter the delay of the relay cutout time. Select
1 of 2 internal mechanical relays in an array
function. See parameter 5-40 Function Relay for
details. If the selected event condition changes
before a delay timer expires, the relay output
is unaected.
Illustration 3.8 O Delay, Relay
If the selected event condition changes before the on
delay or o delay timer expires, the relay output is
unaected.
3.6.4 5-5* Pulse Input
The pulse input parameters are used to
dene
an
appropriate window for the impulse reference area by
conguring
the scaling and
lter
settings for the pulse
inputs. Input terminals 29 or 33 act as frequency reference
inputs. Set terminal 29 (parameter 5-13 Terminal 29 Digital
Input) or terminal 33 (parameter 5-15 Terminal 33 Digital
Input) to [32] Pulse input. If terminal 29 is used as an input,
set parameter 5-01 Terminal 27 Mode to [0] Input.
