Axis %1 drive %2 conversion factor between motor and load too large

%1 = NC axis number %2 = Drive number

The conversion factor from the motor system [increments] to the load system [pm/mdeg] is larger than 1 or the factor which converts the load system to the motor system is larger than 65535.

Conditions:

The condition for the factor load system to motor system is: pm_to_incr <= 65535 The condition for the factor motor system to load system is: incr_to_pm <= 1 with pm_to_incr = 1 / incr_to_pm Formula for rotary axis:

The following applies for rotary motor encoder and rotary axis:

incr_to_pm(n) = (MD1321 SAFE_ ENC_ GEAR_ DENOM(n) / (MD1322 SAFE_ ENC_

NUMERA(n)) * incr_to_pm_rot_rotax

with n = 0 ... 7 (gear stage) and

incr_to_p m_rot_rotax = (360000 / 8192) * (1 / MD1318 SAFE_ENC_RESOL)

MD 1318 SAFE_ENC_RESOL (number of encoder lines per revolution)

MD 1321 SAFE_ENC_GEAR_DENOM[n] (encoder/load gear denominator)

MD 1322 SAFE_ENC_GEAR_NUMERA[n] (encoder/load gear numerator)

Formula for linear axis:

The following applies for rotary motor encoder and linear axis:

incr_to_pm(n) = (MD1321 SAFE_ ENC_ GEAR_ DENOM(n) / (MD1322 SAFE_ ENC_ NUMERA(n)) * incr_to_pm_rot_lin

incr_to_pm_rot_lin = (1000 / 8192) * (1 / MD1318 SAFE_ENC_RESOL) * MD1320

SAFE_ENC_GEAR_P ITCH

Explanations:

MD 1318 SAFE_ENC_RESOL (number of encoder lines per revolution)

MD 1320 SAFE_ENC_GEAR_PITCH (spindle pitch)

MD 1321 SAFE_ENC_GEAR_DENOM[n] (encoder/load gear denominator)

MD 1322 SAFE_ENC_GEAR_NUMERA[n] (encoder/load gear numerator) n = 0 ... 7 (gear stage)

Request: During boot-up of the control.

-    Mode group not ready.

-    Channel not ready.

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

Please inform the authorized personnel/service department. Check the following safetyrelevant MDs depending on the motor encoder type and axis type and correct, if necessary.

MD 1317 SAFE_ENC_GRID_POINT_DIST Grid division linear scale (for linear encoder) MD 1318 SAFE_ENC_RESOL Encoder marks per revolution (for rotary encoder)

MD 1318 SAFE_ENC_RESOL

MD 1320 SAFE_ENC_GEAR_PITCH (for rotary encoder and linear axis)

MD 1321 SAFE_ENC_GEAR_DENOM

MD 1322 SAFE_ENC_GEAR_NUMERA (when using a gear)

The motor encoder type and the axis type are determined via MD 1302: $MD_SAFE_IS_ROT_AX.

Switch control OFF - ON.
