Operating Instructions
Select which ramp to use. Logic '0' selects
ramp 1 while logic '1' selects ramp 2.
Activates 14-10 Mains Failure. Mains failure
inverse is active in the Logic '0' situation.
An active input in bit 0 selects AI54 as the
reference source (see parameter group 3-1*
References, option [35] Digital input select).
An inactive input selects AI53.
Selects Hand or Auto Start. High = Auto On
only, Low = Hand on only.
The input terminal, for which the [52] Run
Permissive has been programmed must be
logic '1' before a start command can be
accepted. Run permissive has a logic 'AND'
function related to the terminal which is
programmed for [8] Start, [14] Jog or [20]
Freeze Output. This means that to start
running the motor, both conditions must be
fulfilled. If [52] Run Permissive is
programmed on multiple terminals, it only
needs to be logic '1' on one of the
terminals to carry out the function. The
digital output signal for Run Request ([8]
Start, [14] Jog or [20] Freeze output)
programmed in parameter group 5-3*
Digital Outputs, or parameter group 5-4*
Relays, is not affected by [52] Run Permissive.
A signal applied puts the frequency
converter into Hand mode as if [Hand On]
has been pressed and a normal stop
command is overridden. If disconnecting the
signal, the motor stops. To make any other
start commands valid, assign another digital
input to Auto Start and apply a signal to
this. [Hand On] and [Auto On] have no
impact. [Off] overrides Hand Start and Auto
Start. Press either [Hand On] or [Auto On] to
make Hand Start and Auto Start active again.
If there is no signal on neither Hand Start
nor Auto Start, the motor stops regardless of
any normal Start command applied. If a
signal is applied to both Hand Start and
Auto Start, the function is Auto Start. If
pressing [Off], the motor stops regardless of
signals on Hand Start and Auto Start.
A signal applied puts the frequency
converter into Auto mode as if [Auto On]
has been pressed. See also [53] Hand Start.
Uses the input as an INCREASE signal to the
digital potentiometer function described in
parameter group 3-9* Digital Pot.Meter.
Uses the input as a DECREASE signal to the
digital potentiometer function described in
parameter group 3-9* Digital Pot.Meter
Uses the input to CLEAR the digital potenti-
ometer reference described in parameter
group 3-9* Digital Pot.Meter

[60] Counter A (Terminal 29 or 33 only) Input for increment
(up) counting in the SLC counter.
[61] Counter A (Terminal 29 or 33 only) Input for
(down) decrement counting in the SLC counter.
[62] Reset Counter Input for reset of counter A.
A
[63] Counter B (Terminal 29 and 33 only) Input for
(up) increment counting in the SLC counter.
[64] Counter B (Terminal 29 and 33 only) Input for
(down) decrement counting in the SLC counter.
[65] Reset Counter Input for reset of counter B.
B
[66] Sleep Mode Forces the frequency converter into sleep
mode (see parameter group 22-4* Sleep
Mode). Reacts on the rising edge of signal
applied.
[78] Reset Resets all data in 16-96 Maintenance Word to
Preventive 0.
Maintenance
Word
[80] PTC Card1 All digital inputs can be set to [80] PTC Card
1. However, only one digital input must be
set to this option.
[85] Latched Pump Starts deragging.
Derag
Options [120] - [138] are related to the cascade controller
functionality. For more information, see parameter group
25-** Cascade Controller.
[120] Lead Pump Starts/stops the lead pump (controlled by
Start the frequency converter). A start also
requires applying a system start signal e.g.
to one of the digital inputs set for [8] Start.
[121] Lead Pump Forces alternation of the lead pump in a
Alternation cascade controller. 25-50 Lead Pump
Alternation must be set to either [2] At
Command or [3] At Staging or At Command.
25-51 Alternation Event can be set to any of
the 4 options.
[130 Pump1 The function depends on the setting in
- Interlock - 25-06 Number of Pumps. If set to [0] No,
138] Pump9 then Pump1 refers to the pump controlled
Interlock by RELAY1 etc. If set to [1] Yes, Pump1
refers to the pump controlled by the
frequency converter only (without any of
the built-in relays involved) and Pump2 to
the pump controlled by the relay RELAY1.
Variable speed pump (lead) cannot be
interlocked in the basic cascade controller.
