Parameter Description
[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
Preventive parameter 16-96 Maintenance Word to 0.
Maintenance
Word
[80] PTC Card1 All digital inputs can be set to [80] PTC Card
1. However, only 1 digital input must be set
to this option.
[85] Latched Starts deragging.
Pump 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, for
example to 1 of the digital inputs set for [8]
Start.
[121] Lead Pump Forces alternation of the lead pump in a
Alternation cascade controller. Set parameter 25-50 Lead
Pump Alternation to either [2] At Command
or [3] At Staging or At Command.
Parameter 25-51 Alternation Event can be set
to any of the 4 options.
[130 Pump1 The function depends on the setting in
- Interlock - parameter 25-06 Number of Pumps. If set to
138] Pump9 [0] No, then Pump1 refers to the pump
Interlock controlled by relay1 and so on. 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 relay1. Variable
speed pump (lead) cannot be interlocked in
the basic cascade controller.
See Table 3.14.
