4.2.1 Default Function Changes for Digital Inputs and Outputs
Default settings for some of H1- and H2- parameters have been modified for the A1000 drive for crane applications. The
changes are summarized in the following tables. Shaded cells show changes from standard A1000 drive.
Digital Inputs
Parameter No. Description A1000 Standard Drive A1000 Crane Drive
H1-03 Terminal S3 Function 24 – External Fault 24 – External Fault
H1-04 Terminal S4 Function 14 – Fault Reset 14 – Fault Reset
H1-05 Terminal S5 Function 3 – Multi-Step Speed Reference 1 0 – Brake release Check
H1-06 Terminal S6 Function 4 – Multi-Step Speed Reference 2 3 – Multi-Step Speed Reference 1
H1-07 Terminal S7 Function 6 – Jog Frequency Reference Select 4 – Multi-Step Speed Reference 2
H1-08 Terminal S8 Function 8 – External Baseblock N.O. 9 – External Baseblock N.C.
Digital Outputs
Parameter No. Description A1000 Standard Drive A1000 Crane Drive
H2-01 Terminal M1-M2 Function 0 – During RUN 21 – Brake Release Command
H2-02 Terminal M3-M4 Function 1 – Zero Speed 0 – During RUN
H2-03 Terminal M5-M6 Function 2 – Speed Agree 2 – Speed Agree
Some digital input, digital output, and analog input functions were replaced with new ones or deleted. For a complete list
of the I/O functions that are available in the A1000 crane drive see section 5.6.
4.3 Operating Without a Brake Sequence
The A1000 crane drive is configured by default to operate with an external brake sequence. If you wish to operate the
drive without an external brake sequence, the following parameters should be changed from their default values to those
listed below.
Parameter No. Description (units) Default New Value Comments
S1-03 Brake Delay Frequency (Hz) 3.0 0.0 Closed Loop Vector default: 0.0 Hz
S1-04 Brake Delay Time (s) 0.30 0.00 Closed Loop Vector default: 0.00 s
S1-09 FWD Torque Compensation (%) 50 0
Parameter in OLV and CLV only.
Closed Loop Vector default: 0 %
S1-14 Slip Prevention Frequency (Hz) 3.0 0.0 Closed Loop Vector default: 0.0 Hz
S1-15 Slip Prevention Time (s) 0.30 0.00 Closed Loop Vector default: 0.00 s
S1-16
SE1 Detection Time (s)
0.30 0.00
S1-17 SE2 Detection Time (s) 1.00 0.00
S1-18 SE3 Detection Time (s) 0.50 0.00
S1-19 SE4 Detection Time (s) 0.50 0.00
See Section 7.1.6
Note:
Although the Dwell function was deleted from the A1000 crane drive software, it is possible to implement it using the
parameters in the S1 group as listed below. Be aware that it may be necessary to modify other parameters in the S1
group in addition to those listed below in order to avoid an oPE22 parameter setting fault. For more information on this
fault see section 8 of this manual.
S1-03 Dwell Reference at Start
S1-04 Dwell Time at Start
S1-14 Dwell Reference at Stop
S1-15 Dwell Time at Stop
When implementing the Dwell function in this manner, the Brake Release Check function should not be set to any of the
multi-function digital inputs. It is also important to note that if the output frequency is less than the level set in S1-14, the
