Description / Notes
P061 Selection relay output RL1 0 - 13
[6]
Value Relay function Active 4
0 No function assigned (relay not active) Low
1 Inverter is running High
2 Inverter frequency 0.0 Hz Low
3 Motor run right has been selected High
4 External brake on (see parameters P063/P064) 1 Low
5 Inverter frequency less than or equal to minimum
frequency
Low
6 Fault indication 2 Low
7 Inverter frequency greater than or equal to setpoint High
8 Warning active 3 Low
9 Output current greater than or equal to P065 High
10 Motor current limit (warning) 3 Low
11 Motor over temperature (warning) 3 Low
12 Closed loop motor LOW speed limit High
13 Closed loop motor HIGH speed limit High
1 External brake requires 24 V (max.) dc slave relay.
2 Inverter switches off (see parameter P930 and section 5).
3 Inverter does not switch off (see parameter P931).
4 ‘Active low’ = relay OPEN. ‘Active high’ = relay CLOSED.
P062 Electro-mechanical brake option
control 0 - 4
[0]
This enables or disables the electro-mechanical brake option.
Operation is the same as for P061 = 4, except that the brake control
voltage is supplied directly.
0 = Disabled
1 - 3 = Do not use
4 = Enabled
P063 External brake release delay
(seconds) 0 - 20.0
[1.0]
Only effective if the relay output is set to control an external brake (P061
= 4) or the electro-mechanical brake option is used (P062 = 4). In this
case when the inverter is switched on, it will run at the minimum
frequency for the time set by this parameter before releasing the brake
control relay and ramping up (see illustration in P064).
P064 External brake stopping time
(seconds) 0 - 20.0
[1.0]
As P063, only effective if the relay output is set to control an external
brake (P061 = 4) or the electro-mechanical brake option is used (P062 =
4). This defines the period for which the inverter continues to run at
the minimum frequency after ramping down and while the external
brake is applied.
Notes: (1) Settings for P063 and P064 should be slightly longer
than the actual time taken for the external brake to
apply and release respectively.
(2) Setting P063 or P064 to too high a value, especially
with P012 set to a high value, can cause an
overcurrent warning or trip as the inverter attempts to
move a locked motor shaft.
