– Application of the Edit Mode (Z145.2– Mode Bit 4 = 1):
 No undesired transmission ratios occur in Edit Mode!
145.5 Speed limit master axis
Display of maximum editable speed (= Position Change) at the transmission input (mas-
ter axis) to prevent overrun at the transmission output (slave axis). The value is calculated
based on the current transmission factors.
If the set value of the master axis exceeds this value, a error will be issued and the sub-
sequent drive will be blocked. Monitoring may occur with an incorrect setting of the trans-
mission factor or a faulty set value of the master axis. Normally, these high speeds cannot
occur.
The maximum possible value (= 2147483647 Inc/T
ab
) is displayed at the transmission in-
put for |Z145.3– Rot. Slave axis| < Z145.4– Rot. master axis.
The sampling time T
ab
in the unit of Parameter Z145.5– corresponds with the effective
position controller cycle (refer to Z1.8– RT0 cycle time).
Example:
Position controller cycle = 250 µs  Inc/T
ab
= Inc/
250µs
Z145.3– revolution of the slave axis = -55555
Z145.4– revolution of the master axis = 1000
 Z145.5– Speed limit

= 2147483647 * 1000 / 55555
= 38655092 Inc/

 The result converted to a rotative speed:
Speed limit = 38655092 * 4 Inc/ms = 1546220368 Inc/ms
= 1546220368 * 60000 / 2
