Note: The minimum value is automatically set to the demagnetization time of the VSD (calculated during quick
commissioning). Inputs smaller than the demagnetization time will not be accepted.
P1263 De-Bypass time
Time delay before a request to switch back to the VSD is acted upon.
Unit: s Min: 0 Def: 1.0 Max: 300.0
Level 2
P1264 Bypass time
Time delay before a request to switch to mains is acted upon.
Unit: s Min: 0 Def: 1.0 Max: 300.0
Level 2
P1265 Bypass frequency
Mains frequency
Unit: Hz Min: 12.00 Def: 50.00 Max: 650.00
Level 2
P1266 BI: Bypass command
Mains frequency
Unit: - Min: 0:0 Def: 0:0 Max: 4000:0
Level 2
Index: P1270[0]: ”Auto” mode (CDS)
P1270[1]: ”Hand” mode (CDS)
P1270[2] BI: Enable Essential Service Mode (Fire Mode)
Unit: - Min: 0:0 Def: 0:0 Max: 4000:0
Level 3
Index: P1270[0]: ”Auto” mode (CDS)
P1270[1]: ”Hand” mode (CDS)
P1271[2] CO/BO: Essential Service Mode (Fire Mode) control word 1/2
ESM Control words will take priority contol over VSD function once ESM has been activated
via DIN. For the ESM control word to take priority it is first necessary for CW1(in000) to be
activated (set bit00=1).
Unit: - Min: 0 Def: 0 Max: 65535
Level 3
Index: P1271[0]: ESM control word 1
Bit00 ON/OFF1 ignored as drive is always forced to run
Bit01 OFF2: Elect. stop always set
Bit02 OFF3: Fast stop always set
Bit03 Pulse enable always set
Bit04 RFG enable always set
Bit05 RFG start always set
Bit06 Setpoint enable always set
Bit07 Fault acknowl. always set
Bit08 JOG right 0 NO, 1 YES
Bit09 JOG left 0 NO, 1 YES
Bit10 Not used
Bit11 Reverse 0 NO, 1 YES
Bit13 MOP up 0 NO, 1 YES
Bit14 MOP down 0 NO, 1 YES
Bit15 CDS Bit 0 (Hand /Auto) always reset (forces “Auto” mode)
P1271[1]: ESM Control Word 2
Bit00 Fixed freq Bit 0 0 NO, 1 YES
Bit01 Fixed freq Bit 1 0 NO, 1 YES
Bit02 Fixed freq Bit 2 0 NO, 1 YES
Bit03 Fixed freq Bit 3 0 NO, 1 YES
Bit08 PID enabled 0 NO, 1 YES
Bit09 DC brake enabled 0 NO, 1 YES
Bit11 Not used
Bit12 PID disabled 0 NO, 1 YES
Bit13 Ext. fault 1 ignored
P1300 Control mode
Controls relationship between speed of motor and voltage supplied by the VSD.
Unit: - Min: 0 Def: 2 Max: 23
Level 3
Settings: 0=V/f with linear characteristics
1=V/f with FCC
2=V/f with parabolic characteristics
3=reserved
4=reserved
5=reserved
6=reserved
19=reserved
20=reserved
21=reserved
22=reserved
23=reserved
Note: P1300=1: V/f with FCC
* Maintains motor flux current for improved efficiency
* If FCC is chosen, linear V/f characteristic is active at low frequencies
P1300=2: V/f with a quadratic curve
* Suitable for centrifugal fans / pumps
P1310 Continuous boost
Defines the boost level in [%] relative to P0305 (rated motor current) applicable to both linear
and quadratic V/f curves.
Unit: % Min: 0.0 Def: 50.0 Max: 250.0
Level 3
Dependency: Setting in P0640 (motor overload factor [%]) limits the boost.
Note: The boost values are combined when continuous boost (P1310) used in conjunction with other boost parameters
(acceleration boost P1311 and starting boost P1312). However, priorities are allocated to these parameters as follows:
P1310 > P1311 > P1312.
Increasing the boost levels increases motor heating (especially at standstill).
